At that point they are already Strings.

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 ?

I'm trying to test this in Pharo 3. I get

KeyNotFound: key #FOO not found in PlatformIndependentEnvironment PlatformIndependentEnvironment(OSEnvironment)>>at: in Block: [ KeyNotFound signalFor: aKey ] UndefinedObject>>ifNil: PlatformIndependentEnvironment(OSEnvironment)>>at:ifAbsent: PlatformIndependentEnvironment(OSEnvironment)>>at: UndefinedObject>>DoIt OpalCompiler>>evaluate OpalCompiler(AbstractCompiler)>>evaluate: SmalltalkImage>>evaluate: EvaluateCommandLineHandler>>evaluate: in Block: [ ...

Does the environment access depend on NativeBoost?

No they are not - Strings and Characters in Pharo are using plain

Unicode encoding internally.

Thanks for the update, and the reference link.
