How can I parse CSV data, assuming that the string is encoded in Shift-JIS?

I have tried the parse_csv routine from the Perl Cookbook, and it works fine on ascii encoded strings, but as soon as I start using shift-jis, which is a multi-byte character encoding, I end up with wierd results, because sometimes it matches in the middle of a character.

Right now I am using a real parser working character by character, but it is really slow... The problem comes from this line, I think:

my $sjis = q{ [\x00-\x7F] |[\x81-\x9F\xE0-\xFC][\x40-\x7E\x80-\xFC] |[\xA0-\xDF] }; @chars = $text =~ /$sjis/gox;
Any ideas on how to speed this/avoid backtracking?

This may involve more programming than you're interested in, but you can use Jcode at CPAN to come up with your own multibyte char techniques. It's very nice. It might improve your parser to a point where the regexes look more logical.
