It still doesn't make much sense, but I don't want to start Japanese lessons here...
Anyhow, some DBMS default the character encoding to ASCII (or ISO8859), not UTF, and Western developers often don't care.
I don't speak Japanese, I just went to translate.google.com and entered some text to get a sample. I can't even remember what I entered.
Oh yeah you're probably right about that. Good work. By the way, any suggestions on that phrase? I'm not a native speaker so my Japanese isn't very good.
