Using Romanian keyboard with gVim

I'm using gVim to type in a journal paper that contains a lot of occurences of the unicode characters U+0219 "s with comma below" (ș) and U+021b "t with comma below" (ț).

Both encoding and fileencoding are set to utf-8, and the GUI font I'm using, Consolas, clearly supports these characters, yet Vim shows them on screen as question marks. That wouldn't bother me too much, except it saves the file to disk with the question marks as well!

Update: Looks I can paste the character into Vim from clipboard, I just can't type it. I'm using the "Romanian (Programmers)" keyboard, and ș is bound to AltGr+s, or Ctrl+Alt+s. Could there be some keybinding conflict with gVim on Windows?

It is possible to use correct diacritics characters on Windows XP, 7 by hacking Windows XP and Windows 7.

Namely using the ISO-8859-16 (code page 28606) from ReactOS and setting it as ISO-8859-2 (code page 1250).

I've described the technique and I've put screenshots here: http://groups.google.com/group/diacritice/msg/2cac27bfd2269cb4

I've also put a video tutorial which shows how to do this on Windows XP: http://www.youtube.com/watch?v=X_q8H-dd1KI and on Windows 7: http://www.youtube.com/watch?v=oqyAEFEpZlg

Bonus you will get emacs and putty working too!
