How to get Unicode output from cl.exe?

Hello,

 

I have a code that runs "cl.exe" by CreateProcess. Then I parse the output from "cl.exe". All works fine with English characters. But if output contains non-English characters, I get "???????" instead of non-English characters.

How can I run "cl.exe" in such mode (to get Unicode output)?

What names should I use for pipes?

What value should I set to "VS_UNICODE_OUTPUT", and what does this value mean?
