    How to display extended ASCII characters in LINUX

    Hi.
    I need help displaying extended ASCII characters on a BASH prompt using the C programming language.
    I used to do this all the time when I had my windows notebook, but it crashed.
    I used this

    printf("%c", 178);

    but this only prints extended ASCII when using DOS or an emululator.
    The ASCII value or code 178 is a graphic type of character that won't display on bash with the above code.
    Is there a header file I can include and some different syntax that I could use to make this happen?

    Thanks.

    No programming language is perfect. There is not even a single best language; there are only languages well suited or perhaps poorly suited for particular purposes.

    Another thread - how do i printf("") to the console?

    I assume you're trying to print "▓", U+2593 DARK SHADE. On Linux, you could try:
    Code:
    #include <wchar.h>
    #include <locale.h>
    
    int main()
    {
        setlocale(LC_ALL, "");
        wprintf(L"\u2593\n");
        return 0;
    }

    When I run that code I get a warning that states-
    "universal character names are only valid in C++ and C99.
    Does this mean I will need the G++ compiler to use these characters?
    Thanks.

    I should probably state that I am running 32bit Ubuntu 9.10 with the most recent edition of GCC, I think its GCC 4.3 or 4.4 something??

    No. use:

    gcc -std=c99
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge
