utf8kind(3)			 Arcan Lua API			   utf8kind(3)

NAME
       utf8kind	- Quick	check an offset	into a string

SYNOPSIS
       state
       utf8kind( offset	)

DESCRIPTION
       Built-in	 support  for internationalized	strings	is fairly rudimentary,
       although	the render_text	class of functions handle UTF 8	internally, no
       such support has	been mapped into the built-in LUA  VM .	This  function
       is  a  quick  helper  to	 determine if you're about to corrupt a	UTF -8
       string or not. state values: 0 =	7bit character,	1 = start of char, 2 =
       middle of char.

NOTES
       1      This is very primitive and was  added  before  we	 included  the
	      bitopts-	Lua  JIT  extension into the codebase. It does not di-
	      rectly help for validating UTF 8 sequences,  only	 for  avoiding
	      obvious truncation.

EXAMPLE
       function	utf8kind0()
	     a = "";
	     for i=1,#a	do
		   print(utf8kind(a[i]));
	     end
       end
