i want to print all ASCII characters kind of like a table, but i really don't have an idea of how to do it, i don't know if there is a built-in method or something to accomplish this, if not
View 2 RepliesHow can I filter ASCII quotes( ' ) and double quotes ( " ) so that I can replace them with the UTF-8 equivalent?If I copy text from a Word Document(ASCII), and upload it to a web page with PHP. The Database(UTF-8) will replace these racters with incorrect character(s).I need some function that will replace these characters but I don't know how to differentiate the ASCII quotes and the UTF-8 Quotes without (somehow) converting the string to hex, then preg_replace'ing the hex code for the symbol.

Suppose user entered ∞ in the text field. I should get ∞ in my log too. However, I got weird characters in return.
What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.
I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?
How can I use extended ascii characters, like ALT + 2 + 0 + 0 for instance? I'm using some of those characters for my passwords for online accounts made under MS Windows and it seams I'm unable to use them in Slackware 13. For instance: if I type ALT+2+0+0 in Pidgin there is no character displayed and if I type in the Terminal the same thing, it will replace my shell prompter (sasser@HOSTA:~$) with (arg: 200):
sasser@HOSTA:~$
(arg: 200)
Say you wanted to write a bash script for "hello world" but the characters were shifted up or down by one.
How would one go about this?
Example:

I am working on a project where I am dialing out of a modem!! Old stuff, ya, but the modem allows my device send info from remote sites from my datibase through a phone line so that this IT departments dont have to worry my device being a security issue on their networks.
Any way, the modem I'm using isn't incredibly well designed, and when a certain ascii char is read by the modem, it reads it as an EOF indicator. It is also important that the files I send are compressed.
My question is: Does anyone know of a compression format that allows ME to dissallow IT's use of certain ascii chars?
just as an illustration:
Device --------> Modem ---------> Off-site
and the Modem stops talking to the device when a certain char is passed to it.
Banshee (Version 1.5.2) doesn't seem to support cover art for tracks that include non ascii characters in any way. All manual methods that work with ascii tracks failed (folder.jpg in album folder, copying appropriately named jpg in ~/.cache/album-art, embedding jpg in mp3 metadata). This is really quite a drawback for users who don't have an English-only music collection. Is there any workaround or bugfix that I missed or do I have to go back to Rhythmbox to have non-English cover art?

I'm working on a Qt program and when it gets to the following line of code I get a seg fault:
QString blah = QString::fromAscii(entry->d_name, 256);
entry->d_name is a 256 byte character array returned by readdir(), I would expect this line of code to convert that character array from ascii to a QString, but I get a seg fault and I'm not entirely sure why..

I've got lines of data in the following format:
space1=number of times error has occured
space2=IP address
space3=Error
I've set this out nicely with printf and made it email me, the problem is - it's not entirely clear what each column/space is and the IP and occurances can sometimes seem confusing. Is there any (easy) way to output this into an ascii like table? There will always be 5 occurances, and the format will always be the same
To start off I would like to acknowledge that I am not a very good C programmer and pretty much everything I know has been self taught through mostly trial and error. So forgive me if there is an obvious answer to my question, or if I don't immediately grasp the concepts involved in the possible solution.
Basically, I'm writing an application which will be creating log file entries rather rapidly (potentially hundreds per minute), and I would like each new line to appear at the top of the log file, rather than the end. Opening a text file in append mode is easy enough, but I can't seem to find any obvious way to do the opposite.
I have been looking online and it seems that there exists no standard way to do this, and I have only been able to find a few mentions of how somebody might achieve it. The most common method seems to be using two files and copying the data back and forth between them. This seems like it would be insanely I/O intensive with the number of lines I'm likely to be generating. If this is the best method to use, I will give it a shot; though I am not 100% clear on how to implement it, I am also open to any other ideas as to how to accomplish this, and I don't have to worry about portability since the program already uses Linux-only libraries. So calling out to sed or something is not necessarily out of the question (though I imagine performance would also be an issue there).
To know the function on checking whether a character is ascii or unicode character. From the following [uRL]. The function IsTextUnicode is related to Windows VC++ library. I would like to know the library/function which provides such facility.

I have a very basic program which I wrote, to print the integer equivalents of an ASCII character. The code is below:
Code:
#include<stdio.h>
int main(void)
{
char c;
[code]....
The code is supposed to take a character as input and print the integer equivalent of that character. But the problem is that, after printing the integer equivalent, it prints an extra '10', every time.
Code:
f
102
10
[code].....
Why does this extra '10' always come? When the code is just a simple:
Code:
#include<stdio.h>
int main(void)
{
[code]....
The code works just fine. There is no extra '10' displayed. I am using Ubuntu 9.10 with gcc-4.4.1.
I'm working on my ncurses application, written in C. I get user input through a loop which uses getchar(). I was able to recognize Ctrl-n by comparing the keypress to ASCII character 16, and this seems to work fine. However, if I noticed that the ASCII character for Ctrl-j (10) is the same as the Line Feed. I tested this, and if I press enter on the keyboard I get the same ASCII value as when I press Ctrl-j.
So, what do I do if I want Ctrl-j to mean something different in my program than pressing enter?The ncurses terminal mode is set to raw, with a 100 millisecond timeout, and keypad is on (I'm already using the up and down arrow-keys).

View 3 Replies View Relatedsplitting a string by every nth characters. I'm using Python 2.7.1 because I'm using older libraries, if that matters.
For example, if this is my input:

Splitting it by every 10th character should produce this list:

I 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?
My goal is to send escape characters from Linux to make scanner's LED blink. I've started with a simple "beep" command:
echo -e "�7"
and it worked. We are using WaveLink emulator and the escape sequences for the LED are
echo -e "�33%150;200;5L"
Linux returns me this: 150;200;5L
So, it doesn't work. What am I doing wrong for the LED sequences?
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?
For example, I have a file called "file" like this one:
type=strongsubj len=1 word=absolve pos=verb stemmed=y priorpolarity=positive
type=strongsubj len=1 word=unique pos=adj stemmed=n priorpolarity=neutral
type=strongsubj len=1 word=absolutely pos=adj stemmed=n priorpolarity=neutral
type=weaksubj len=1 word=taking pos=verb stemmed=y priorpolarity=positive
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
type=weaksubj len=1 word=usually pos=adverb stemmed=n priorpolarity=positive
type=strongsubj len=1 word=purecolor pos=anypos stemmed=n priorpolarity=negative
type=strongsubj len=1 word=accusingly pos=anypos stemmed=n priorpolarity=negative
I want to add the plural for the noun, for example if find this line:
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
will add one more line :
type=weaksubj len=1 word=friends pos=noun stemmed=n priorpolarity=positive
where we add "s" for the word friend
I did try to do like that:
<code>
cat file | while read LINE ; do
set -- ${line}
if [[ "${4#pos1=}" == "noun" ]];then
#I tried this line but it doesn't work properly:
v3==$(echo $line |sed 's/$3/$s') #I want to find the third word "word=friend" in that line and add "s" after that word
# I don't know what command to add this new line "$v3" to the file ???
done
