Simple unicode example not working

If i try to execute this code:

Code:

---

#define _UNICODE
#include <tchar.h>
#include <stdlib.h>


int main() {

TCHAR c[]=_TEXT("something");

system("PAUSE");
return 0;

}

---

I get the following compile errors (i am using Dev-c++4):

Code:

---

In file included from c:\docume~1\deviance\desktop\x\untitl~2.c:2:

What am i missing? :(
If i add:

Code:

---

wprintf(L"This is working: %lc",123);

---

i get further errors.

Code:

---

wchar_t mystring[] = L"flipcode";

---

doesn't work either.
Can u tell me what i'm doing wrong. And perhaps give a a working sample o code so i can get the idea. Thank you.

#define UNICODE and _UNICODE.

It still doesn't work. But i've just come across #include <wchar.h>
in win32sdk helpfile. This code seems to work:

Code:

---

#define _UNICODE
#include <wchar.h>
#include <tchar.h>

int main() {
TCHAR c[]=_TEXT("ceva");
wchar_t mystring[] = L"something";

wprintf(L"This is working: %lc",123);
wprintf("%ls",c);
wprintf("%ls",mystring);

system("PAUSE");
return 0;

---

Actually only the first wprintf works. The other 2 don't. Why? :confused:

> TCHAR c[]=_TEXT("ceva");
I thought these were declared by windows.h

Hmm :D I seem to have figured it:

Code:

---

wprintf(L"%ls",c);

---

Code:

---

wprintf(L"%ls",mystring);

---

i've noticed this:

Code:

---

wprintf(L"This is not working: ->%lc<- ",301);
 wprintf(L"This is working: ->%lc<- ",201);

---

The not working wprintf prints: "This is not working: ->", but not the 301 character as well.I guess it has to do with local unicode settings so that the compiler knows what character to print on the screen coresponding to 301. But how do i "tell him" that? :confused:

301 and 201 are stupid numerical constants that dont match the conversion specifier. Store them in a TCHAR.
TCHAR letter1 = 0201;
TCHAR letter2 = 0301;

edit: You need to prefix octals with a zero. Sorry I didn't notice you were using octals before, but you will probably get something like

$ ./a
This is working �
This is not working Á

because in octal the ISO-8859 character map doesn't start until 240.

I doesn't work. What i'm trying to do is print "Ş" (which is 350 in windows character map) on the screen. So what must i write? :confused: (i noticed that wprintf(L"%lc",350) doesn't work.)

> wprintf(L"%lc",350) doesn't work.
Of course not. I'm working under the impression that you are using base eight numbers. 350 in decimal is completely different from 350 in base eight. Stick to one number convention.

How about
TCHAR letter = 'Ş';
wprintf(L"%lc is a letter\n", letter);

instead of fumbling around the character map? Because unless you are actually making windows use the language you're writing in, number magic isn't going to work.

Because I'm using Latin-1 for instance, 0350 on the map is ª and it would print that, not what you want.

I can't! I can't type nor paste "Ş" in the editor window (Dev-c++4). It pastes "S," :confused: So what now? p.s. i am not using base eight numbers. should i? :confused:

Switch the language that the keyboard maps to temporarily to the language you're working with, and then type it. If you don't know how to do that, then you probably should just type in English.

I've done so. I was able to type it but the program still didn't print anything. I'm telling you there is a different problem. But i don't want to upset anybody. I'll see what i can do myself.

That is because you are still using Latin-1 as the character set on your system. You need to code your program to set it's locale correctly

#include <locale.h>

if (!setlocale(LC_ALL, "")
fprintf(stderr, "Could not set the locale\n");

where in the code above, the program will load the character set specified in your OS' environment variables. If you do it this way then all you would have to do is boot up your computer in a different language and run the program, then the output should work.

If you want to specify what language you're working with (and force other people using your program to read a language they might not know), then you would have to type a specially formatted string like they teach you how to in the man page, to use the proper character set. Either way, you're pretty stuck with the locale library.
