Basically, anything pre-E220 (ie, earlier than 2006) we don't care much
about.

But about the patch...  mm_charset_take_and_convert_to_utf8 does a few
things for UCS2:

1) checks if the string is in hex by looking for (len % 4) and xdigit
2) if hex, attempts to convert the hex
3) if not, attempts to convert to UTF8

What operator was triggering the problem?  If there are operators like
"3abc" then yeah, it would get misconverted.  Just curious here.
