lj_char.c (1980B)

      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/
