You might want to do a search for discussions on supporting Unicode / UTF-8 in
the Linux console/terminal - since this uses bit-mapped fonts and the problems
may be similar.
Also maybe try to find out how these scripts are supported in mobile phones and
what font formats these devices use.
e.g. in the Middle East cell phones are available which can display Arabic; in
India inexpensive phones are available which can display about several different
Indic scripts - & in Lhasa since last year you can get phones which allow you to
send SMS messages in Tibetan. All of these are "complex" scripts.
For all these scripts there are many characters and combinations of characters
which are rarely if ever used in everyday / modern text - and probably don't
need supporting on most small devices with a limited or particular application.
