Using vi mode in ksh I noticed that the command endword (vi.c) gets
staked when the last character in a word is a UTF-8 character.
To reproduce:
In the line bellow, using vi mode, first move your cursor to the first
character, then hit "e" several times. You'll see the cursor get
stacked in the euro sign.
$ word word€ word
^ this is an euro sign.
The following diff is one of my intuitive C newbie solutions, some
expert will surely find a better one.
