C51: WIDE CHARACTER SUPPORT
Information in this article applies to:
I must implement UNICODE using Wide Characters in C. I noticed that in STDLIB.H in the INC directory the following is defined:
#ifndef _WCHAR_T_DEFINED_ #define _WCHAR_T_DEFINED_ typedef char wchar_t; #endif
Shouldn't wchat_t be defined as an unsigned int or and unsigned short?
Yes. It probably should. However, the Keil C51 Compiler V6 and earlier does not support wide characters.
The tools do not use this data type, so you are free to change it to whatever suits your needs. Note that printf and the other library routines to not support wide characters. So, you'll have to write your own routines to provide that support.
We may incorporate wide character support in future releases of the tools.
