Is it possible to allow set up of a different font per
each IM Engine?
If you use several engines, and do not have font that
supports all of them, you have to go to the
configuration panel to change font used in the input
It may be as simple as having to switch fonts for
simplified/traditional Chinese input, or more
complicated/useful if you use a mix of languages that
do not have a "common" font (this may include your own
developped font and IME, private use area that may
contain different glyphs at the same code points
depending on usage context etc).
