PATCH: charmap: Copy field uses default font.

Charmap.exe, tested on ReactOS and in Windows 7, the lower text box shows characters in the default font for a text box (I think it's Tahoma), instead of the currently selected font.
This may be trivial, but it is annoying because say I copied 10 characters, needed to remove some but didn't know which is which because they were Wingdings.

NOTE: I did attempt to patch this but wierd things started happening, and it only worked once then didn't.
