Knox default falls back to ISO-8859-1 encoding instead of UTF-8.
I did some research and the default encoding specification has changed over the
years. It looks like ISO-8859-1 was the default historically, but currently it
should be UTF-8.

There are very few cases where ISO-8859-1 and UTF-8 are incompatible and it
would be outside the default ASCII charset.
I also found that the default XML encoding is UTF-8 so even if we don't change
all the defaults to UTF-8 we should do so for XML.
