Possible to add new precomposed characters for local language in Togo?

[Philippe Verdy]

Consider this source code (based on Microsfot "kbd.h", even if it is ported
to ReadOS)

https://doxygen.reactos.org/d7/df4/kbd_8h_source.html

Look for the structures named with "LIGATURE"

And now look at the special entry value "WCH_LGTR"=0xF002 (i.e. a PUA),
which indicate these keys are mapped using those "LIGATUREn" structures
(which have arbitrary lengths in WCHAR/UTF-16 code units), instead of
storing a 16-bit code unit directly.

<kbd.h> predefines LIGATURE1 to LIGATURE5 but longer lengths are possible
(see cbLgEntry and nLgMaxd members in the KBDTABLE structure)

The table of ligatures in linked from the pLigature member of the KBDTABLES
structure, which points to the first set of LIGATURE1 mappings.

Now study more precisely how _KBDTABLES is defined <kbd.h> and documented
in MSDN...
