You don't need this anymore. The libc locale is ignored because
slnunicode has its own UTF-8 functions.

Entering this into an UTF-8 encoded source file, I get:


Maybe your source file is still in ISO-8859-1 encoding?

Try: iconv -f iso-8859-1 -t utf-8 <oldfile >newfile

I think the library initializer function is buggy. It relies on
some internal Lua functions and also returns the unicode.utf8
table whereas it should really return the unicode table itself.

[Klaus Ripke are you reading this?]

To fix this remove the 'lua_pop(L, 1);' in line 1324 and add a
'lua_settop(L, 2);' just before the final 'return 1;'. Now
recompile: cc -shared -Wall -Os -fpic -o slnunico.c
And try the test cases: lua unitest
