Hi,
I agree with Thomas that Unicode is promising, at least in terms of encoding
the characters. However, rendering Unicode in a readable form can be a major
task. This is especially true for non-alphabetic writing systems, where glyphs
of the writing system may not actually be represented in Unicode, but are
instead generated by a rendering engine. The available font rendering engines
which can actually display Unicode text accurately are few and far between. In
terms of corpus processing I am aware of no system which actually renders
Unicode accurately for all languages. Help is on the horizon:
1.) I believe Mike Scott is working on a version of Wordsmith which may both
read Unicode text and render it appropriately.
2.) I am currently working with the GATE team at Sheffield towards making a
version of GATE which renders a wide range of writing systems encoded in
Unicode, but it is laborious work.
3.) SIL international are developing a font rendering engine called Graphite
which should be able to be embedded in corpus processing systems.
So while I think Unicode is the way for corpus work to go in the future,
treading that path with non-alphabetic writing systems at this moment in time
is somewhat difficult.
