Re: regexp on utf8 string

The good thing about functions such as ucfirst is that they're locale-friendly. You don't really have to worry about what upper-case characters map to what lower-case characters in a given character set; ucfirst knows. Try this:

my $string = "word1 word2 word3";
$string = join ' ', map { ucfirst } split /\s+/, $string;

It ought to do the trick. ...just one way to do it.

A slightly more robust regexp solution might include the following:

use strict;
use warnings;

my $string = "word1 word2 word3";
$string =~ s/(\w+)(?=\W|$)/ucfirst $1/eg;

I finally manage to do the tricks with these: uppercase the first letter and lowercase the rest `$string = "\u\L$string";` [download] my string always contains spaces and/or dashes so I uppercase each letters which follows one or more spaces or dashes. `$string =~ s/([\s-]+)(.)/$1\u$2/g;` [download] Regards, Frederic	[reply] [d/l] [select]
