How to print Unicode character in C

Question

I am trying to print a Russian      U 0444 CYRILLIC SMALL LETTER EF  character  which is given a code of decimal 1092  Using C    how can I print out this character  I would have thought something along the lines of the following would work  yet     int main        wchar t f    1060      cout  lt  lt  f  lt  lt  endl

I needed to show the string in UI as well as save that to an xml configuration file. The above specified format is good for string in c++, I would add we can have the xml compatible string for the special character by replacing "\u" by "&#x" and adding a ";" at the end.

For example : C++ : "\u0444" --> XML : "ф"

Ultimately  this is completely platform-dependent  Unicode-support is  unfortunately  very poor in Standard C    For GCC  you will have to make it a narrow string  as they use UTF-8  and Windows wants a wide string  and you must output to wcout      GCC std  cout  lt  lt          Windoze wcout  lt  lt  L

To represent the character you can use Universal Character Names  UCNs   The character     has the Unicode value U 0444 and so in C   you could write it   u0444  or   U00000444   Also if the source code encoding supports this character then you can just write it literally in your source code      both of these assume that the character can be represented with    a single char in the execution encoding char b     u0444   char a           this line additionally assumes that the source character encoding supports this character   Printing such characters out depends on what you re printing to  If you re printing to a Unix terminal emulator  the terminal emulator is using an encoding that supports this character  and that encoding matches the compiler s execution encoding  then you can do the following    include  lt iostream gt   int main         std  cout  lt  lt   Hello    or  u0444  n       This program does not require that     can be represented in a single char  On OS X and most any modern Linux install this will work just fine  because the source  execution  and console encodings will all be UTF-8  which supports all Unicode characters    Things are harder with Windows and there are different possibilities with different tradeoffs   Probably the best  if you don t need portable code  you ll be using wchar t  which should really be avoided on every other platform   is to set the mode of the output file handle to take only UTF-16 data    include  lt iostream gt   include  lt io h gt   include  lt fcntl h gt   int main          setmode  fileno stdout    O U16TEXT       std  wcout  lt  lt  L Hello   u0444  n       Portable code is more difficult

1060  is four characters  and won t compile under the standard  You should just treat the character as a number  if your wide characters match 1 1 with Unicode  check your locale settings    int main         wchar t f   1060      wcout  lt  lt  f  lt  lt  endl

In Linux  I can just do   std  cout  lt  lt         I just copy-pasted characters from here and it didn t fail for at least the random sample that I tried on

Special thanks to the answer here for more-or-less the same question  For me  all I needed was setlocale LC ALL   quot en US UTF-8 quot    Then  I could use even raw wchar t characters

When compiling with -std c  11  one can simply    const char  s    u8  u0444     cout  lt  lt  s  lt  lt  endl

Another solution in Linux   string a        cout  lt  lt        xd0 xa4      lt  lt  hex       lt  lt  int static cast lt unsigned char gt  a 0          lt  lt  int static cast lt unsigned char gt  a 1     lt  lt        lt  lt  a length    lt  lt   B    lt  lt  endl   string b    v   cout  lt  lt   v    xe2 x88 x9a      lt  lt  hex       lt  lt  int static cast lt unsigned char gt  b 0          lt  lt  int static cast lt unsigned char gt  b 1          lt  lt  int static cast lt unsigned char gt  b 2     lt  lt        lt  lt  b length    lt  lt   B    lt  lt  endl

If you use Windows  note  we are using printf    not cout      Save As UTF8 without signature  include  lt stdio h gt   include lt windows h gt  int main         SetConsoleOutputCP 65001        printf    n        Not Unicode but working - 1251 instead of UTF8     Save As Windows 1251  include  lt iostream gt   include lt windows h gt  using namespace std  int main         SetConsoleOutputCP 1251        cout  lt  lt       lt  lt  endl
