From time to time, new characters are added to the unicode standard.For instance, in 2008 a capital sharp s (upper case form of German eszett)was added at position 0x1e9e.What actions need to be taken in order to make the new character part of the various fonts we use on our desktops?
View 1 RepliesI wrote a java program that writes strings to a file. The strings contain foreign language characters. When I run the program in Windows, the output file shows the foreign characters. However, when I attempt the same operation in Linux, the output file shows a white question mark in a black background instead of the foreign characters. The same Linux system could display the foreign characters if I copy the output file from Windows to Linux. I tried to create the output file using gedit that my program would then add additional strings to and chose Unicode-32 for encoding but still the same problem.
What could I do to get the program to display the foreign language characters from output text file?
I am working on an application that will convert English text into equivalent Indian language text. Since Unicode is the standard, I will be using it. In most of the western languages each code-value directly refers to the glyph index and placing the code-values side by side will give the required display. This one to one mapping is not possible in Indian languages where rendering syllables is required rather than rendering just consonants and vowels. Many of the complex characters are made up by combining several unicode values.
My question here is: How Linux renders this Unicode text correctly? More specifically, what package is used? I believe in Windows they use Uniscribe for rendering.I believe there will be an operating system library for handling the text rendering. Or do I need to write my own rendering engine? How programs like Firefox, GEdit shows unicode text? Do they also have proprietary engines for correct rendering?
Say I want to write some of the more exotic Unicode characters to a file, what's the proper way to do it? when decimal integers are involved, we use %d for floating point we use %f and for hex we use %p.What's the equivalent marker for Unicode values that C understands?

View 5 Replies View RelatedI'm using openSUSE 11.2 with GNOME dual-booted with Windows 7, been installed from scratch for like a week. The bottom line is: Nautilus displays a series of matrices, "x"s and other symbols instead of characters in Hebrew.
Screenshot:
Now, it worked fine at the beginning but once I started installing updates it went. I installed a whole bunch of updates and programs so I don't know what changed it. The weird part is (as you can see in the screenshot) that the shortcut to the left of a Hebrew-named folder shows up correctly only the first time Nautilus opens after starting. So as soon as I closed the Nautilus window after taking the screenshot and reopened it, it also displayed like the others. The screenshot is of my ntfs Windows drive, however the problem occurs in my home folder as well.
Here's my fstab anyway:

View 9 Replies View RelatedI recently intalled Debian lenny and I'm having issues with some of the unicode characters. Instead of displaying the symbols properly it shows one of the following depending on font/app:
1) Square outline with four letters/numbers arranged inside
2) Just a blank square outline
3) Just a blank space
I haven't been able to test all possible characters, but from a quick check it seems that Cyrillic works properly, Japanese doesn't.A few Google searches later and I'm no wiser on how to fix the issue. Any help?
My terminal shows unicode squares (the little square with it's 2 byte unicode value inside it), whenever I press a control character while running a program (ex. cat or ping).See this example. Here I show the key's I pressed then turn off echoctl, and repeat the sequence. http://imagebin.ca/img/mXbutJ1.png
the 0003 is when I pressed Ctrl+C, and the 001A is when I pressed ctrl+z.Can anybody tell me why this is or how to turn it off. This is inside a gnome-terminal session, though I don't think it's gnome-terminal.If, inside this exact same bash session I open screen (by typing "screen"), it doesn't do this anymore, and ctrl+c/z/etc is completely quiet.
For some unknown (to me) reason, "Ctrl+Shift+u, <unicode number>" doesn't work in F12. I had gotten quite used to this method in order to input several symbols and if you know what you want, it is a lot faster compared to using the character map. This was working in all recent Fedora versions.Does anyone know how to enable this functionality?

While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?

View 1 Replies View RelatedI tried defining CLOCK_MONOTONIC_RAW in the include file. The timer does not run correctly.I am looking for a timer that I can count on to get a time delta.In my /usr/include/bits/time.h I have CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID defined. I assume they are not based on the realtime clock (not changed when time is updated. All I really need is a way to determine delta time when running. mili-seconds would be great, 1/100th second is preferred, and 1/10th would be acceptable.

Please have patience and read on. This is a rather convoluted situation.The company currently does (since 1994) a loop cycle based task execution process. They tasked me to run a particular task at a particular interval. This is where I found the loop process and how much time delta time there can be.I want to implement a time based version. Nothing really drastic, just call the task when the timer says so. I know how I want to do it, they just keep throwing roadblocks in the way.The latest one is "what if someone changes the time ?". I looked on the web and my research seems to indicate that if I use clock_gettime(CLOCK_REALTIME,&ts) that indeed delta time can be messed up if something tinkers with the time.
The other option is to use CLOCK_MONOTONIC_RAW instead of CLOCK_REALTIME. It is indicated that this can not be changed and would be good for this type of application. The problem is I don't know if it is implemented in the version the company distributes, Red Hat Linux Release 7.2 (Enigma). Anyone know anything about this?Again, the company distributes it's product that runs on Red Hat 7.2. They have many units in the field. I read on the web that 1) There is no tick and 2) Red Hat 6 has the CLOCK_MONOTONIC_RAW implemented. Well, I looked at /usr/include/bits/time.h and found CLOCK_REALTIME but not CLOCK_MONOTONIC_RAW.
I have my OpenSuse 11.1 box set up with utf-8, however, every time I try to open a file with utf-8 characters with vi it can't handle those characters properly.

A more comprehensive phrased question since I lost access to the other one.I would ask that the other one be deleted, not this one, as it should not have been migrated in the first place.There are currently two NTFS drivers available for Linux.
The NTFS driver included in the kernel, and the userspace NTFS-3G driver that makes use of FUSE.By all accounts, NTFS-3G works perfectly.My question then, is if the NTFS filesystem has been successfully reverse engineered, why have the kernel NTFS team not implemented the changes in their driver? At the moment it is still marked as experimental, and there is a good chance it will destroy your data.
let me show you my config and tell me if its ok
Its pretty simple:
eth2 -> 192.168.1.0
eth2:0 ->192.168.50.0
eth1 and eth0 are the net interfaces, 1 router each to provide wan failover (not implemented here)
Hosts:
loc1 eth2:192.168.1.0/24
loc50 eth2:192.168.50.0/24
Interfaces
net6 eth0 detect
net7 eth1 detect
- eth2 192.168.1.255,192.168.50.255
Masq
eth0 eth2
eth1 eth2
eth2 eth2
Policy
all all ACCEPT info
Rules
SECTION NEW
REJECT loc50 loc1 all
Zones
fw firewall
net6 ipv4
net7 ipv4
loc1 ipv4
loc50 ipv4
Problems / Doubs:
1) Is the hosts file required?
2) I guess I need doing masq from local to each external, and also from local to local even if they share the same interface, hence the eth2 eth2 in the masq file...
3) So is shorewall well implemented in these scripts to handle aliases?
I am now at my 6th version of my opensuse build and I can't get it to start the graphical login.I am trying my build out on a VirtualBox using the live cd.This is what happens during installation :It will install properly. No error messages at all. I get the (graphical) options screen to select language and screen resolution settings, so far so good.I select the default (top) installation for my opensuse and hit enter.Then I will get the verbose progress and when it's finished, the verbose will ask me for my user name and password.Then I enter those correctly and the verbose will tell me to enjoy.I am then left with a blinking cursor, and don't know what to do next.
This is not what should have happened since in my build I had selected Configuration > Startup > Default runlevel > 5: Graphical loginI can find no reason for this failure since on my Windows system I have tried out several other Linux systems in the same way and never experienced this problem before.During the assembling of my packages I have payed close attention to select all packages required for a graphical login.An other problem is that although I selected the default language for my build to be Dutch, the default language during setup is still English.I hope there is someone who would be kind enough to be prepared to help me out, I am so eager to start trying out my self made OS.

I'm trying to write a Perl script that will convert text to ASCII. I'm particularly interested in converting files created with MS Windows, so I used Notepad to create a few test files.
I have had some success with the following script:
[[ Script Deleted -- see subsequent posts ]]
After coming back /home/ to Debian, I used file to examine the file types:
$ file ansi.txt unicode_big-endian.txt unicode.txt utf8.txt
ansi.txt: ASCII text, with CRLF line terminators
unicode_big-endian.txt: Big-endian UTF-16 Unicode character data, with CRLF line terminators
unicode.txt: Little-endian UTF-16 Unicode character data, with CRLF, CR line terminators
utf8.txt: UTF-8 Unicode (with BOM) text, with CRLF line terminators
After running:
$ uni2ascii.pl -i ansi.txt -c ASCII -o new_ansi.txt
$ uni2ascii.pl -i unicode_big-endian.txt -c utf16 -o new_unicode_big-endian.txt
$ uni2ascii.pl -i unicode.txt -c utf16 -o new_unicode.txt
$ uni2ascii.pl -i utf8.txt -c utf8 -o new_utf8.txt
Everything appears good:
$ file new_ansi.txt new_unicode_big-endian.txt new_unicode.txt new_utf8.txt
new_ansi.txt: ASCII text
new_unicode_big-endian.txt: ASCII text
new_unicode.txt: ASCII text
new_utf8.txt: ASCII text
But the "little-endian file" does not convert properly:
$ md5sum new_ansi.txt new_unicode_big-endian.txt new_unicode.txt new_utf8.txt
c4def7932bc151b9e786b6ca1299162c new_ansi.txt
c4def7932bc151b9e786b6ca1299162c new_unicode_big-endian.txt

c4def7932bc151b9e786b6ca1299162c new_utf8.txt
When I use cat to print the new_unicode.txt file in an Emacs terminal, a ^@ appears on the last (empty) line. When I open the new_unicode.txt with KWrite, a warning message tells me that the file is a "binary" and "saving it will result in a corrupt file."
