Unicode support needed

[KelvinShadewing]

As it is, the engine only seems to support ASCII characters between 0 and 127, and it's not the bitmap test fonts I'm using, as those are full CP-437 fonts. In order for games to show languages other than English, many languages require Unicode. I've tried adding Unicode myself, but to no success. I added #define SQUNICODE, which set Squirrel to Unicode mode, but that caused a ton of compile errors. After fixing all those errors, by converting normal strings to wchar_t arrays as needed, it compiled, but then started throwing segfaults as soon as it launched.

I've found conflicting information on converting char and wchar_t, and the functions I came up with to convert them are as follows:

wchar_t* towc(const char* s) {
	const size_t csize = strlen(s) + 1;
	wchar_t *wsarg;
	mbstowcs(wsarg, s, csize);
	return wsarg;
};

char* tostr(const wchar_t* s){
	char* csarg;
	wctomb(csarg, *s);
	return csarg;
};

These could be the issue.

The rest of the code is basically just adding L to the beginning of every string. I've added a folder with the Unicode edits made here.
