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.

View 1 Replies View RelatedI'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:

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
5b62a013dced4f2c2c0af45ea6388c1e new_unicode.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."
the problem is how to have a "backslashed R", looking at here and picking up Combining Diacritical Marks you can see all the unicode combining diacritical marks like the one to have a "slashed R" that is U+0338, so if you type R and ctrl>shift>U 0338 >return you obtain R̸,but if you want a "backslashed R" and you type R and ctrl>shift>U 20e5 >return you obtain R⃥, and it isn't what you wantto do this you can use also gucharmap or kcharselect, I tried and them work for U+0338 and doesn't work for U+20e5, so, thinking that it was a gucharmap problem I mailed to gnomebugs here , I red this too here:
Combining Diacritical Marks for Symbols U+20D0 U+20FF (84008447)
Windows: Arev Sans, Arial Unicode MS, Cambria Math, Caslon, Code2000, EversonMono, Free Sans, Free Serif, Hindsight Unicode, Monospace, Reader Sans, RomanCyrillic Std, SImPL, sixpack, STIXGeneral, Sun-ExtA, Symbola, Y.OzFontN
Unix: Caslon
and installed fonts, Arial Unicode MS and Caslon, that seems to support U+20D0 - U+20FF (my is U+20e5, so it should be in the range) Combining Diacritical Mark, but it doesn't work, and at the end him suggest me to ask help to my "distrution's support forums", so here I am , Why I cannot have a "backslashed R"??
I'm used to holding the left Alt and entering the ASCII character whenever I'm using an unknown keyboard configuration and want to type a special character. For example, Alt-092 makes a backslash (). That's on Windows. Is there a way to do this in Ubuntu ?
Note : I also want to be able to use this in console mode. That means I don't want a solution involving a software with a GUI.
Is there a known tool to convert a file consisting of 2 byte Hex into ascii?
Note: - Maintain file offset listing in bytes code...
To encrypt the text, we take the word "python" and make it at least the same size as "welcome home" by repeating it as follows:
w e l c o m e h o m e
p y t h o n p y t h o n
Then, we convert each letter into its numerical ASCII value as follows:
w e l c o m e h o m e = 119 101 108 099 111 109 101 032 104 111 109 101
[Code].....
And, finally, we convert the numbers back into their corresponding ASCII character:
But what is the easiest way to figure out the Unicode number of a character when you already have the character?
For instance, I pasted this character here from a PDF:
Code:
#include <iostream>
using namespace std;

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

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?
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 8 Replies View RelatedWell, I have a web application in Linux server. All my Java codes are there. FYI, whenever user entered non-ASCII characters(e.g. ∞,�,�) in a text field in my web application, and I check the log of my Java code in Linux server, it returns weird characters.
Suppose user entered ∞ in the text field. I should get ∞ in my log too. However, I got weird characters in return.
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 Replies View RelatedI'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).
Is there a good open-source Unicode string library for C++ (or C)?

Code:
#include<stdio.h>

Code:
f

Why does this extra '10' always come? When the code is just a simple:

int main(void)

The code works just fine. There is no extra '10' displayed. I am using Ubuntu 9.10 with gcc-4.4.1.

For alpha , it does not allow me to input data which has spaces such as " hello world".
