Unicode character text entry for search doesn't work

[firecat53]

It's gonna take a different entry method for unicode support. The curses textpad doesn't seem to support it (at least not that I got to work, anyways). getstr() does, but it's editing is limited to backspace.

Two projects to check how they do unicode entry:
