Jim: I too have access to a manual Korean typewriter; about half the
bars attached to what hits the ribbon are angled to allow building the
full character. It also has ribbon problems so I don't use it.

 Jim: Different products require different levels of display quality. I
doubt that one set of orthographic rules would satisfy everyone. Vendors
will develop output software with a particular users in mind. This is
fine. My hope is that a continuum of quality could be defined for various
scripts to help users assess different vendor's offerings. For roman
script output could vary from telegraphic all caps to all the way
to elegant ligatures and kerning so capital A following capital W overlap
or appear to have the right space. Is it unrealistic to hope that such a
continum or lists of capabilities could be devised for various scripts?
   Sorting is another topic deserving a list of its own for each langauge
or script. For roman script Librarians have long had filing rules. Like
other standards, there are several, in the U.S.: 1. American Library
Association, and 2. Library of Congress. I suspect no software completely
follows either rules. (For example, filing roman numerals as numbers
conflicts with some Polish one letter prepositions.) I do not know enough
about filing other scripts to say what is wanted, but suspect opinions
vary. (For example, some want a Devanagari letter with a candrabindu to
file before one with none.) Again, rather than a single rigid code one
could perhaps hope to specify various levels of excellence and then ask
vendors what their product supports.
