2** Character types.
3** Donated to the public domain.
4**
5** This is intended to replace the problematic libc single-byte NLS functions.
6** These just don't make sense anymore with UTF-8 locales becoming the norm
7** on POSIX systems. It never worked too well on Windows systems since hardly
8** anyone bothered to call setlocale().
9**
10** This table is hardcoded for ASCII. Identifiers include the characters
11** 128-255, too. This allows for the use of all non-ASCII chars as identifiers
12** in the lexer. This is a broad definition, but works well in practice
13** for both UTF-8 locales and most single-byte locales (such as ISO-8859-*).
14**
15** If you really need proper character types for UTF-8 strings, please use
16** an add-on library such as slnunicode: http://luaforge.net/projects/sln/
