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

Question

I am using GCC. I have a string containing the hex value of a UTF-8 char like this:

char[] str = "4e86"

(such kind of strings are read out from an xml-file). I would like this to convert this to a wchar containing the character \u4e86.

I know I can directly define

wchar_t wc = L'\u4e86';

but I would like a function like this

wchar_t wc = convert(str)

How?

Answer 1

Try this:

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