ByteString, according to the primitive. So if the shell supplies e.g. UTF-8 strings for command-line parameters, which the VM sees as bytes, then the ByteString instances answered by getSystemAttribute: would need decoding, right?
In your case, they must already be wrong at that point.
Not necessarily. The getSystemAttribute: primitive doesn't do decoding. Perhaps it should.
Yes, probably. I just tried on Mac OS X, Pharo 4:
$ export FOO=élève-Français
$ echo $FOO élève-Français
$ ./pharo Pharo.image eval 'OSPlatform current environment at: #FOO' 'élève-Français'
$ ./pharo Pharo.image eval '(OSPlatform current environment at: #FOO) asByteArray utf8Decoded' 'élève-Français'
The question is, is this true for all platforms ? Windows ?
Certainly not :-) On UNIX systems the encoding is undefined AFAIK. You may want to consult locale before deciding on encoding - this works quite well. nl_langinfo() is the guy to ask. Best, Jan

No they are not - Strings and Characters in Pharo are using plain Unicode encoding internally.
Thanks for the update, and the reference link.
