plan9port completely ignores XCompose because it has its own compose
mechanism (which is mapped to the same key). The sequences are defined
in /lib/keyboard and need to be compiled in.
Support for the BQN unicode characters is achieved by generating the
necessary lines for /lib/keyboard from the .inputrc (for GNU readline)
that is part of mlochbaum/BQN (simply because that file is somewhat
parseable and stores the sequences in ASCII, contrary to .XCompose).
This is implemented by a small BQN script which is executed in
postPatch.
All usual sequences are supported except those that map to the second
ASCII character of the sequence. These exist to keep certain characters
typeable in other input system. Thanks to the explicit compose key,
Plan 9 doesn't have this problem.
