How to convert a string containting the hex value of a UTF-8 to a wchar in C? -


i using gcc. have string containing hex value of utf-8 char this:

char[] str = "4e86"

(such kind of strings read out xml-file). convert wchar containing character \u4e86.

i know can directly define 

wchar_t wc = l'\u4e86';

but function this

wchar_t wc = convert(str)

how?

try this:

char[] str = "4e86"; wchar_t wc = strtol(str, null, 16);
