Yes, in theory we don't need the entries in locale.alias.

I have just took a look at it, and I am sure that it is also based
on the old BIG5_1984 standard. So I think it should be fixed.

My opinion is: we could try to unify the character set standard
(including the mapping to Unicode) as much as possible. I propose
to maintain only one charmap, say, the charmap in glibc-2.2, and
any other charmaps found in the other places could be generated
from the one in glibc-2.2 via simple perl scripts. That is the
way we created the big5.c, the iconvdata of glibc-2.2. If you
take a look at the comments in big5.c, you will find a lot of
perl scripts to generate contents of it from the BIG5 charmap.

Using this way, we could try our best to have a unique standard
of the charmaps in most parts of the system.

Besides, I could not understand very well about the format of

	/usr/lib/X11/fonts/encodings/large/big5.eten-0.enc

the following are lines from the original version of X401src-2.tgz:

-------------------------------------------------------------------
  STARTENCODING big5.eten-0
  ALIAS big5-0
  # This file is partly derived from data provided by the Unicode Consortium
  SIZE 0xFA 0xFF
  ^^^^^^^^^^^^^^
what is the meaning of SIZE???


  STARTMAPPING unicode
  # The Unicode table is probably not quite correct
  UNDEFINE 0x0000 0xF9D5
  ^^^^^^^^^^^^^^^^^^^^^^
what does this mean????

and in the end of this file:

  STARTMAPPING cmap 3 3
  ^^^^^^^^^^^^^^^^^^^^^^
what does this mean????
------------------------------------------------------------------------

Could any one tell me? Thanks :-)
