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:

Does the environment access depend on NativeBoost?
