Hello Nicholas.

I played little bit more with the code and different settings and found what was the difference between those two versions.

First - you use "wide" ncurses - ncursesw. I use ncurses.
Second. GoldEd incorrectly initializes ncurses in reverted version (like it was before I started to make any changes in GoldEd code). ncurses documentation explicitly says that before call initscr(), locale has to be set with setlocale. Otherwise it will use incorrect settings. Most probably plain C locale. I kinda get picture very similar to yours.

Did you have an issue with non-English chars when scrolling the message? What I see in UFT-8 terminal now - most of unicode text displayed correctly and pseudo-graphic too. Only pseudo-graphics lines broken similar to yours. And when I scroll text down - it corrupts.

If you may try to add one line of code to latest master and try it - that would be helpful.

goldlib/gcui/gkbdbase.cpp
line 149, right before initscr add this:

setlocale(LC_ALL, "");

If that gives you expected result - I'll push this change to master.

Hope you still want to dig this. :)
