88939 - Korean JOHAB encoding <-> Unicode converter

Status: VERIFIED FIXED

(Core :: Internationalization, defect)

Description

[Jungshik Shin]

Korean JOHAB encoding is an encoding to encode all
11,172 modern Hangul syllables as well as ~4800 Hanjas(Chinese
characters) and ~1100 symbols (in KS X 1001) in 2byte-encoding-space
(with MSB of the first byte set to 1). Because of the way
Hangul syllables are encoded in JOHAB (use 5 bit-long bit
pattern to represent Hangul consonants and vowels), algorithmic
conversion is possible between Unicode and JOHAB as far
as 11,172 Hangul syllable is concerned while for Hanja
and symbols, table-look-up is necessary. This has been
already included in intl/uconv/src/{uscan,ugen}.c 
to support Sun's ksc5601.1992-3 X11 font encoding. However, this
does not include US-ASCII (which is a part of JOHAB encoding) so that
it cannot be used for generic JOHAB encoding support. Also,
for ksc5601.1992-3 font encoding, JOHAB-> Unicode converter
is not necessary and has not been 'activated' (necessary
lines in uscan.c is commented out ) (refer to
bug 80111 and bug 71489).

  I've made a patch to support full-fledged JOHAB encoding
support (in BOTH direction) and will attach it to meta-bug
I'm going to file later today.
