I’m using Win7 with its PowerShell version 2, it works for me. But I suppose it depends on your Windows’ locale encoding. For you, I think “Western European” might work. But try to save your script in UTF-16 BE with BOM. Normally, if you use “Windows PowerShell ISE”, it would take care of it.
However, if your Windows’ locale is not Western European, I’m afraid that would not work and me too, I’m waiting Microsoft to fix this bug.
Telling people “… to not use those characters” is so dumb! Sorry to say so. Come on, we are in the 2nd decade of the 21st century and Unicode is still not supported? It’s like we’re using computer in the 80’s. That’s so archaic!
Not only is it dumb to tell people to not use those characters, it’s also a lack of respect to others’ culture and language.
Come on Microsoft. Wake up!
