Jeff,
Let's plan on meeting early next week to finally put
to bed all the FLNX/Microwindows font issues. You or Scott
can hack FLNX, and I'll hack Microwindows, and we need
to make sure that T1, TrueType, and GB2312 chinese fonts
all work with FLNX. Then let's go after the interal (I suggest
UTF-8) encoding format. You and Scott might want to look
at all this to get prepared to hack it into submission.
In particular, the following needs to happen:
FLNX:
1. Font names are consistent, no chinese recompile should be
required. That is, only Microwindows is recompiled, not FLNX
or ViewML. There needs to be a way to specify that a chinese
font is wanted, rather than say Western truetype.
2. Known font names will be used, and font name aliasing will
be added to Microwindows.
3. Internal text encoding UTF-8 standard will be used. (or
at least mult-byte, rather than UC16 wide characters)
Nano-X:
1. Add font aliasing, and font directory configuration files,
readable at run-time.
2. Possibly add run-time selection of chinese vs truetype,
rather than having to recompile. This might allow GB2312
chinese fonts to be image-loaded, rather than bound-in.
3. Allow GB2312 and UTF-8 encodings to run simultaneosly,
with the addition of another MWTF_GB2312 type.
4. Get approval for all chinese fonts used in Microwindows, as
part of the standard distribution.
ViewML: (post 0.2)
1. Run ViewML using UTF-8/GB2312 internally. Allow
HTML conversion to this format and display of any HTML
page in Western as well as Chinese.

Greg
