  1. /*
  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/
