That's another example of the Unicode zealot's dismissal of a large
user community with a huge existing base. The majority of the world
doesn't need complex script shaping. Indeed, it's open to question
whether script shaping is *plain text* at all (which is surely why
Unicode dislikes the coding of shaped forms, though it has often been
coerced into doing it). Dismissing a widely used system because it
can't do something that Unicode explicitly doesn't wish to encode is
strange, to say the least.
I personally stick to the core font system because I find bitmapped
fonts far clearer and easier to read than ****type fonts in the sizes
I use - and BDF is a hell of a lot easier to edit than ****type when you need
another character, be it an obscure hanzi or a phonetic symbol. I
gather that many CJK users, who are a non-trivial community, find the
same, hence the rather large effort put into the wenquanyi bitmap fonts.
Incidentally, Wikipedia currently says (under "OpenType") that
Opentype has no font-internal support for complex script shaping. If
that's not the case, perhaps you could correct it?
If it is the case, then what's so different from doing client-side
script-shaping with bitmapped fonts, which you could also do?
(That is a question - I know almost nothing about complex layout, nor
about how OpenType fits with X, since I don't use a language requiring
