Right... That's a limitation of current font formats that needs to be
resolved before the latest version of Unicode can be fully supported by
any one single font.  But you can still support _most_ of it with one
font and there are a few fonts that do... I should not have used any
superlatives (ever! ;o) ) in my first message... :-P  So to support all
of the current version of Unicode, a given renderer currently _needs_ to
support some kind of font switching, ideally based on unicode block not
on module if it has hope of allowing multi-lingual modules.
