Subject: [PATCH] Welcome to hell. Yes, after hours of wrangling with MySQL and
 every version of their JDBC drivers under the sun and poring over hundreds of
 web pages, it appears that this is the "solution" to storing multibyte
 characters in the database.

This means that *every single string* that might contain multibyte
characters has to be jiggered before being entered in the database and
unjiggered upon removal. And if we accidentally forget, things will appear
to be fine until we deploy to one of our multibyte foreign partners at
which point they'll see gibberish. Yay!

Too bad the Chinese didn't invent programming, then all this shit would
just work.
