#!/usr/bn/perl use strict; my $first; BEGIN { $first = "é" }; my $next = "é"; use utf8; my $last = "é"; print "first is ", utf8::is_utf8($first) ? "" : "not ", "UTF-8\n"; print "next is ", utf8::is_utf8($next) ? "" : "not ", "UTF-8\n"; print "last is ", utf8::is_utf8($last) ? "" : "not ", "UTF-8\n"; gives me first is not UTF-8 next is not UTF-8 last is UTF-8 So I would say that it only takes affect for lines after it is used. -- Chas.
