This is totally understandable. :) We will explain to you the best as we
If you want to make a korean keyboard with a key for each letter then you'll
need a keyboard with...
(sit down before next line)
... 11,172 letters, ie from \uAC00 to \uD7A3 + 24 "single letters" or jamos
Of course there is a special method.
The korean keyboard layout is a single qwerty, each key with a "jamo"
The 11172 syllabes are made of combined jamos , and a state machine can be
used to track which keys have been pressed, and how they have to be
combined. See my previous messages for an explanation.
However when I searched the Internet for my use, I did not find a lot of
information on this, so I did the research.
About you soft keyboard, I think the problem can be solved with the use of
plugins, ie a method that takes keystrokes and outputs characters. For
European scripts, the routine will be quite trivial, but for other scripts,
this is needed. With such plugins, we can also imagine support for other
complex scripts such as chinese or indian or whatever. An input method will
then be made of an XML file describing the layout, and a .so to hold the
key->character translation algorithm.
