As long as the locale short name cannot contain characters outside of
ASCII, and I don't see how it could, just the typical
measure-allocate-convert dance, add error handling to taste:

int res = MultiByteToWideChar(CP_ACP, 0, ctype, -1, NULL, 0);
WCHAR *wctype = malloc(res * sizeof(WCHAR));
memset(wctype, 0, res * sizeof(WCHAR));
res = MultiByteToWideChar(CP_ACP, 0, ctype, -1, wctype, wctypelen);

If it is somehow guaranteed that ctype is only the most basic short name
("xx-YY") with no code pages or anything, it becomes much simpler, of
course, and I would just use a loop.

If the locale name can contain characters above 0x7f, we'd have to know
the code page of the string we use to get the code page.
