vim utf-8 multibyte support that is causing these characters to be
created. e.g.  e<backspace>' results in é. sometimes the resultant
character looks almost identical and so I didn't notice. I haven't
found the magic recipe to turn this off (maxcombine=0 doesn't seem
to stop it) or change the special compose sequence, so I'll keep
looking.
