I've come up with a new set of tables, and a Python program (that's
only a bit more complicated than it needs to be) to generate
transmaps.h from them.

Because the tables are separate, they can be updated more easily and
new character sets that recode doesn't understand can be added.

To download the Python `transmaps' and the tables I've done so far, see:

I think it would be a good idea for the transmaps.h generated from
this to go into tn5250, once everyone's happy with the character sets
included, since it fixes incorrect mappings in most of the character
sets.
