Attach minimal source to reproduce this. This notification should be supported already. Also note that there's no TTN_NEEDTEXT, instead there's TTN_NEEDTEXTA and TTN_NEEDTEXTW.
I can only report what I see. If you don't want to believe it or just run the attached application to verify, so be it.
This bug reporting system is a big joke!
