SYNOPSIS
use Unicode::CheckUTF8qw(is_utf8);
my $is_ok = is_utf8($scalar);
DESCRIPTION
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.
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.
BUGS
Hopefully not, but mail me if so!
