I used this to get the dialogues working and that has been (mostly ) successful.

I finally figured out (with Steven's help) how to set the CODEPAGE correctly in resource files (set it once and don't set it in the menu definition at the same time). You also need a CODEPAGE capable font and you need to do the prespara call correctly.

It requires that you stop and restart the program between language changes that also require a CODEPAGE change. Thanks for your help.

I plan on releasing a RC tomorrow  which demonstrates this. The menus in all languages show in that language with appropriate glyphs on a CODEPAGE 850 system. The dialogues do also with the Misc page showing each language in the combobox in its own language with proper glyphs (unicode). It still has a few ruff edges but I think has potential.
