Problem upper-casing characters above 0xFF. The following code snippet only changes every other character: 
my $aaa = "aáeéiíoóuúoöuü";
my $bbb = uc $aaa;
print "$aaa\n";
print "$bbb\n";

Any suggestions? Do I finally need to join battle with Unicode?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
