Well, 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.
How 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.

View 2 Replies View RelatedWhat 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?

QString blah = QString::fromAscii(entry->d_name, 256);

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.
If we have a .so library elf in linux, will it be possible to find out the APIs supported by it. Or in other words, the functions that can be used along with the argument types and return type.? Note that we dont have any other header files or documentations related to the library.
View 5 Replies View RelatedI am currently writing an engine using SDL and openGL, and while I've gotten it mostly done, I've never really learned how to read configuration files. The configuration files that I'm hoping on using will be a straight forward syntax using "#" for comments and variables will be declared using "foo=hello". I don't need a lot of items in the configuration files, but enough to change needed settings. I'm not wanting to use external libraries (how are you going to learn if you can't do it yourself? :P) and I'm hoping to write it from scratch. If someone could please point me to a tutorial on how to do this or even some working code I may be able to figure it out. I am using the C programming language also(as I like it more than C++, sorry).
View 5 Replies View RelatedI'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).

I'm trying to make several files: each named after the display and containing resolutions. But for some reason I get null when trying to read lines.
I have a folder which includes bunch of folders each having data files in them. [ Folder A has F1, F2 F3 ..... F1000 folders in it, and F1, F2, F3 ... each has about 10 different files named FILE 1, FILE2, FILE3 .... in them.
I am interested in File 1 of each Folder, because that contains the data I need in it. More specifically, that File1 s have a line "ANSWER=..." in them, and i need to get that value of the ANSWER from each file. So doing it by hand is so hard, so I need to write a script that will scan all folders and give me a list of values of eache ANSWERs.
I've been reading about getopt and getopts but it doesn't seem like it's possible to parse arguments like --foo or even -foo. I've started my own script trying to achieve this, but I'm still wondering if I'm losing performance and if there is a better way to do this task.

I have a binary file, which I need to process using my C++ application. Only thing I know is first chunk of the file is long, second chunk is int, third chunk is char etc... The binary file actually contains something like below. (which is represented in hex base).
D7 07 00 00 00 00 00 00 37 18 00 00 DE 07 ............ so on.....
I need to procees the file in the following way.
* I know the first data segment in my file is long. So it takes 4 bytes.
* so I need to read the first four bytes. That is D7 07 00 00.
* Then I need to reverse this as 00 00 07 D7.
* Finally I need to get the decimal value of above hexa decimal line. ( 00 00 07 D7)
* i.e. 00 00 07 D7 (in hex) = 7D7 (in hex- after removing leading 0 s) = 2007 (in decimal)
Like wise I need to process the whole file.

Actually I have two data files one of them contains 44406 and the other one has 12066 rows and I want to check whether the difference between the components of two specific columns is less than a threshod but I have simplified it here. I had written this code and then I have realized that this code just goes through the number of rows as the same as the first.txt file and ignores the rest. I could not find the problem yet.
I made a string key-value mapping struct in C, and functions to add and remove entries. I would also like to write a function to read in this file format:
Code:
key: value
another: another value
