NAME

6       Unicode::CheckUTF8 - checks if scalar is valid UTF-8
7

SYNOPSIS

9          use Unicode::CheckUTF8 qw(is_utf8);
10          my $is_ok = is_utf8($scalar);
11

DESCRIPTION

13       This is an XS wrapper around some Unicode Consortium code to check if a
14       string is valid UTF-8, revised to conform to what expat/Mozilla think
15       is valid UTF-8, especially with regard to low-ASCII characters.
16
17       Note that this module has NOTHING to do with Perl's internal UTF8 flag
18       on scalars.
19
20       This module is for use when you're getting input from users and want to
21       make sure it's valid UTF-8 before continuing.
22

HISTORY

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