Unicode::CheckUTF8 - checks if scalar is valid UTF-8


   use Unicode::CheckUTF8 qw(is_utf8);
   my $is_ok = is_utf8($scalar);


This is an XS wrapper around some Unicode Consortium code to check
if a string is valid UTF-8, revised to conform to what expat/Mozilla
think is valid UTF-8, especially with regard to low-ASCII characters.

Note that this module has NOTHING to do with Perl's internal UTF8 flag
on scalars.

This module is for use when you're getting input from users and want
to make sure it's valid UTF-8 before continuing.

=head1 HISTORY

This is some old code, dating back to before Perl 5.8 and before
Unicode support in Perl.  I wish I didn't have to keep using this
code, but I can't find any other code on CPAN for UTF-8 checking
that's both sufficiently fast and more importantly, correct.  So now
there's yet another way to do it.


package Unicode::CheckUTF8;

use base 'Exporter';

   $VERSION = "1.03";

   @EXPORT = qw();
   @EXPORT_OK = qw(isLegalUTF8String is_utf8);

   require XSLoader;
   XSLoader::load Unicode::CheckUTF8, $VERSION;

Hopefully not, but mail me if so!
