Yes indeed, itʼs finally rather easy to find: http://accentuez.mon.nom.free.fr/Clavier-CreationClavier.php (again) writes notably (as of the present topic; translation follows below): | aLigature | […] | Le fichier kbd.h ne contient que 4 types LIGATURE2, LIGATURE3, LIGATURE4, | LIGATURE5.

But in reality one is not limited to five code units: if AltGr + space generates ten code units, e.g. as in ‘*LIGATURE*’, the table above can be declared as follows: TYPEDEF_LIGATURE(10) // LIGATURE10, *PLIGATURE10; static ALLOC_SECTION_LDATA LIGATURE10 aLigature[] = { […] }; Thus we can create keys generating words or even sentences. However we are limited to sixteen code units: TYPEDEF_LIGATURE(16).” As of retrieving this page, it is actually the 18th result of Bing Search on 'keyboard layout creation', results in all languages enabled.
