Help Handa-san make the switch to Unicode ;-)

The problem is that the target charset of cp850 is Latin-1, not
Latin-9.  OTOH, in a Latin-9 language environment, non-ASCII
characters typed by the user are by default converted to Latin-9

Yes, as long as the user doesn't type characters that are unique to
Latin-1 and to Latin-9 (like if they use both the currency symbol and
the Euro symbol in the same buffer).  That is, assuming that the
result, probably UTF-8, is not what the users expect.
