When outputting text with UTF-8 combining characters, such as diacritics, the resulting cursor position appears to be internally inconsistent.

I'm attaching a test program that produces different output between Screen and directly in the outer terminal. The displayed text will also change within GNU Screen itself depending on how it gets redrawn (scrolling one line at a time vs. with pgup/pgdn, or switching between panes).

I don't think this is the same as bug #51890 or bug #63634, though it may be related.

Thanks for maintaining GNU Screen!
