Can you trust your terminal emulator to properly handle the output? To me, encoding issues are always a wild goose chase, so I like to eliminate as many things from the encoding dance as quickly as possible. Usually that means that instead of including umlauts (or whatever) in my source code, I use the character names instead: `# instead of use utf8; my $s = "göre";` [download] `# I prefer to use use charnames; my $s = "g\N{LATIN SMALL LETTER O WITH DIAERESIS}re";` [download] This eliminates the issue that my text editor is lying to me. When inspecting the output, I either pipe the output through `hexdump` or through `Data::Dumper` with `$Data::Dumper::Useqq =1;` so the console only sees 7bit ASCII. This eliminates my terminal emulator lying to me. Of course, that does not help with reading data from files that I don't control, but every little step helps.	[reply] [d/l] [select]

"Can you trust your terminal emulator..." Sure, i believe always what Apple tells me ;-) I continue with my investigations.
