Hmm, maybe it is worth thinking about stripping out the portions
of ICU/Pango that apply to scripts from particular regions, and
making region-specific packages of these.

Yes, you are right about the need for converters, and the need for special
fonts, but I believe that this is the only way to get support for complex
scripts on text-based terminals. This will need to be done at some point
for the Linux console, as I doubt that they are ever going to roll support
for complex text handling into the console drivers.

For now, on the OpenMoko hardware, maybe a stripped-down ICU/Pango is the
best solution. Let me think about this.
