Re: [Bug-guile-ncurses] Unicode in form-driver

[Mike Gran]

Sorry.  That was a long shot.

I uploaded to the Git repo an update to guile-ncurses
that will use the Unicode-enabled version of form-driver if
the underlying ncurses supports it.  I tried with Polish characters;
it works for me.  You need to build it on a version of ncurses
from the last few months, however.

I'll make a new release soon.
