Hi,
I need a way to tell if a given string contains non-ascii characters (specifically, Japanese double-byte characters). I thought I might be able to split the string and then call ord on each character, and tell from the results of ord whether it's ascii or not, like this:
@chars = split '', $string; for my $char (@chars) { my $ord = ord $char; print "$char $ord\n"; }
But so far either the split seems to be giving me the wrong number of characters, or ord is trying to force them into an incorrect ascii value.
Anyone have a good way to do this? The next thing I'm going to do is peek inside the Jcode module to see if it has a good trick I can use -- I'll post whatever I come up with.
