Oh, interesting. That reminds me of the fix that I needed for Windows, 
let me see... yes, here it is: LanguageEnvironment 
class>>defaultFileNameConverter needs to be fixed since it is (wrongly) 
guessing the file name encoding based on the currently active locale 
(which makes no sense btw, since the locale doesn't mean Jack for file 
name encodings). Hm ... lemme try this ... ah, interesting. It appears 
that I can make the Umlauts work on Unix correctly if and only if:
* I fix the above method to return UTF8TextConverter in every case [*1]
* I use -pathenc MacRoman -textenc MacRoman
Which makes no sense to me since neither the path nor the text encoding 
is MacRoman but it appears to work. Huh?

[*1] And that of course reminds me that nobody has really made any 
comment on why the hell we still deal with all of these nonsensical 
legacy encodings and don't just go straight to UTF-8 in the VM interface 
which would simplify *lots* of cruft in the code.
