NAME

       ureadkey - Returns the next unicode character from the keyboard buffer. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int ureadkey(int *scancode);

DESCRIPTION

       Returns	the  next character from the keyboard buffer, in Unicode format.  If the buffer is empty, it waits until a key is pressed. You can
       see if there are queued keypresses with keypressed(). The return value contains the Unicode value of the key, and if not NULL, the  pointer
       argument will be set to the scancode. Unlike readkey(), this function is able to return character values greater than 255. Example:

	  int val, scancode;
	  ...
	  val = ureadkey(&scancode);
	  if (val == 0x00F1)
	     allegro_message("You pressed n with tilde
");

	  if (val == 0x00DF)
	     allegro_message("You pressed sharp s
");

       You  should  be able to find Unicode character maps at http://www.unicode.org/. Remember that on DOS you must specify a custom keyboard map
       (like those found in `keyboard.dat') usually with the help of a configuration file specifying the language mapping  (keyboard  variable	in
       system section of `allegro.cfg'), or you will get the default US keyboard mapping.
