Yes, of course. The range 0x0000-0x00FF of Unicode is exactly the same
as ISO-8859-1. The range 0x0100-24FF is a set of Latin characters
except ISO-8859-1 characters.

Since fonts of ISO-8859-* are usually installed in many OSes, I don't
think this is a benefit.

Anyway, I will implement the following algorithm:

If characters of mule-unicode-0100-24ff are found, encodes the draft
with utf-8. Otherwise, tries to find an appropriate character set out
of ISO-8859-*.
