I've noticed that Vim displays the "NO-BREAK SPACE" character (Unicode
00A0) incorrectly for several single-byte encodings (e.g., cp437, cp850
and cp775), which typically encode it as 0xFF.
To reproduce...
:set enc=cp850
Enter the following 2 lines in an empty buffer...
<ff>2345
12345
...where <ff> represents the character at code point 0xff, entered with
CTRL-V.
The non-breaking space is displayed normally (like a regular space
character) until the cursor is moved onto it, whereupon the cursor
becomes 4 characters wide, covering (and effectively erasing) all but
the "5" on the first row. The covered characters are not redrawn when
the cursor is moved down a row with j. If you then use CTRL-L to redraw,
the covered characters are redrawn, but shifted rightward from their
original location. Move the cursor back up to the line with the
non-breaking space, then move it left and right, and you'll see the
characters redrawn in the 2 different spots, sometimes simultaneously.
Vim probably doesn't know that 0xff is a space or any special character.
After setting the 'encoding', you also need to set 'isprint'.
If you set 'isprint' properly, does the problem go away?
No. 'isprint' was already set to the Linux default, which includes 255:
i.e.,
