Hi

A colleague kept complaining today that 5.24's uc produced "SS" from uc("ß")

I tried explaining to him that this is according to standard orthographic rules taught in school.°

(Anyway he kept blaming Perl ... ;-)

NOW ... they actually invented and standardized a capital form some years ago, see https://en.wikipedia.org/wiki/Capital_%E1%BA%9E#Development_of_a_capital_form

Questions

I see a potential upgrading problem arising from there ...

my results with Strawberry Perl so far on a German Win version

    
use strict;
use warnings;
use utf8;

$\="\n";

print "Perlversion $]";

print "$_ -> ",ord($_)  for "ß", "\Uß", uc("ß");

Perlversion 5.032001
ß -> 223
SS -> 83
SS -> 83

°) "ß" is a ligature which developed centuries ago from of two old "s" variants, long story ...

... for comparison, I occasionally see "oe" ligatures in French loan words in English texts
