Hello,
I can't get character classes in regular experession to work with
Unicode characters. I've tried both putting both the literal Unicode
characters and the \x{XX} notation within square brackets [] to create
a character class, but it's not working. I've tried with both the
developer release of Perl 5.7.2 and the daily build from 2002/02/13.
Here's an example of some code that isn't working for me:
---
#!/usr/local/bin/perl5.7.2
use Encode;
use utf8;
$string = encode_utf8("f\x{e9}lise");
$string =~ s/f[e\x{e8}\x{e9}\x{ea}\x{eb}]lise/SUCCESS/; #does not match
print "new string: $string\n";
---
With another approach, this works:
#!/usr/local/bin/perl5.7.2
use Encode;
use utf8;
$string = encode_utf8("f\x{e9}lise");
$regex = encode_utf8("f\x{e9}lise");
$string =~ s/$regex/SUCCESS/; #matches
print "new string: $string\n";
While this does not:
#!/usr/local/bin/perl5.7.2
use Encode;
use utf8;
$string = encode_utf8("f\x{e9}lise");
$regex = encode_utf8("f[\x{e9}\x{e8}]lise");
$string =~ s/$regex/SUCCESS/; #does not match
print "new string: $string\n";
Should examples 1 and 3 be working? Thanks for listening.
