In this case you should convert your database to utf8 (because it
contains utf8 data) asap. SQL_ASCII actually doesn't mean ASCII but
means store whatever octet you throw at it as it is, it's more akin to
binary data (but without the possibility to store 0x00). From your
examples, and with some luck, your database may contain utf8 only
data, but if you connect with different clients or encodings and feed
some latin1 etc. the database will be just happy to accept everything,
no question asked; just, it will be a nightmare to read the data back
or to make it uniform later.

If you don't have familiarity with encodings and relative problems,
the Spolsky article is a nice introduction
