I eventually decided to write new commands, because the above
japanese-* commands are too specific to the Japanese users: for
example, they convert kana characters as well.

So there are now new commands fullwidth-region, fullwidth-word,
halfwidth-region, and halfwidth-word, which will be in Emacs 31 when
it is released.

With that, I'm closing this bug.

M-l runs the command downcase-word.
That's great. But here's a feature request:
Have commands that can change wide to narrow,
with the same ease as M-l.
E.g., change ２０９Ｍ into 209M.
and another command to do the opposite.
OK, I guess they are called fullwidth and halfwidth.
