It seems to me to be most important to handle the Hanja area, since this
is the area we can't handle with the Hangul shaper. (And it's important
to get the glyphs from the KSC5601 font for these so they match the
Hangul in style.)
For the Hangul compatiblity jamos, we can probably just go with your
original suggestion and mark them as with a "" language list rather
than with a "*" language list in the coverage information that the
basic shaper reports.
It's fine if the generation process for tables-big.i involves some
combination of tables we supply (like the TIS table) tables generated
from Unihan.txt and tables that the person generating the table needs
to download from ftp.unicode.org (ISO-8859-* tables and JIS-0201 table)
