Yes, I know the perl unicode implementation is far from user-friendly
or intuitive - this is an upstream issue that is being addressed - but
it does work (just) if used correctly .
perl's lc / uc DO work for UTF-8, IF the UTF-8 is properly encoded, AND perl is
running in wide-character mode , AND the characters have defined upper/lower
case counterparts in your current locale.
These examples should expose the issues - I suggest you also read the
perlunicode and perllocale man-pages .
$ perl -C -e 'use locale; use utf8; use Encode qw(decode);
$s=decode(utf8,"\xc5\x99\xc4\x9b"); print uc $s,"\n";'
ŘĚ
$ perl -C -e 'use locale; use utf8; use Encode qw(decode);
$s=decode(utf8,"\xc5\x99\xc4\x9b"); print $s,"\n";'
řě
$ perl -e 'use Encode qw(decode); $s=decode(utf8,"\xc5\x99\xc4\x9b"); print
$s,"\n";'
Wide character in print at -e line 1.
řě
$ perl -C -e 'use Encode qw(decode); $s=decode(utf8,"\xc5\x99\xc4\x9b");
print
$s,"\n";'
řě
$ PERL_UNICODE=31 perl -e 'use Encode qw(decode);
$s=decode(utf8,"\xc5\x99\xc4\x9b"); print uc $s,"\n";'
ŘĚ
$ PERL_UNICODE=31 perl -e 'use Encode qw(decode); $s=decode(utf8,"ŘĚ");
print
lc $s,"\n";'
