in thread Playing with extended chars

I think the problem is not on the string (I'm using perl5.8.5, because 5.8.0 had some bugs in RedHat), but on the tr operator itself.

The first attemp works like this:

perl -e '$_="áéíóú";tr/áéíóú/aeiou/;print'
aeaoauauau

It seems that "á" is treated as two characters, maybe "´" and "a", and each one get one different matching char ( "a" and "e").

BTW, encode and decode functions return values that make me think that the string is well formed, and that is tr// who's making wrong things. Am I too lost?

    If you have utf8 encoded strings in your program file, you need to use the utf8 pragma (see perldoc utf8). 

    use utf8;

$s = 'holáéíóúon';
$s =~ tr/áéíóú/aeiou/;
print $s;
# prints holaeiouon

    The code above may show the double characters explicitly since perlmonks.org is served as ISO-8859-1.
