primitiveGetenv returns values in the current locale's code page on Windows; a value bound to € returns a stings with single char 128 on MS1252 (western european) at least.
On windows, there are three versions of each api call with string parameters/returns; xxx (depending on UNICODE being defined, either resolves to *A or *W) xxxA (Ascii, or, more accurately, current code page)* xxxW (UTF-16) IIRC, the intention is that primitives receiving/sending char* to the image will expect/return utf8, so a conversion macro before passing it on to the syscall would be necessary on Windows; I believe one exist already and is used in at least the file plugin primitives. Cheers, Henry * The windows FFI fallback used if primitive fails calls the *A version directly, and can be changed to call *W correctly, but there's a fair bit of wrapping fluff involved; https://youtu.be/Um41DPPs5ZA?list=PL843D1D545F9F52B6&t=1591 -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
