ISO-8859-1 is assumed as there is no real clarity wrt the spec. In most cases people
send ASCII so it's not an issue, but for some, the extended characters they send
can cause problems with XML processing.  As stats and YP require UTF8 we need to
translate them and block invalid cases.

For the moment, for non-Ogg streams only, we assume that the metadata needs converting
from ISO-8859-1. Ogg streams are UTF8 so no conversion needed. You can override the
default with a charset mount option.
