Something like the following may help (
encode_monk and
decode_monk are only there to save you potential character set problems with your text editor -- don't let them distract you). Cheers.
use strict;
use warnings;
use Encode 'decode_utf8';
my $suspect = decode_utf8( decode_monk('v~C3~A4hicule') );
warn '$suspect='.$suspect;
if ($suspect =~ /^([\p{IsAlnum}]+)$/) {
warn "MATCHES $1\n";
}
exit( 0 );

## WARNING: Using sprintf here is too expensive. A
