It looks like this flag is simply not supported currently. Do you have an
application that's using it?

I can share binary sample if needed, atm I switched to reactos implementation

It might serve as reference for wine as well

No, I'm talking about real world application that's using it, it's clear how to
produce a test case for this.

For my case, I'm modding a game (FEAR) and dedicated server had issue with this
case, like player uses invalid unicode symbols in nickname, and it causes
server hang, was trying to fix it using this api.
