ligature usage - WAS: How do we find out what assigned code points aren't normally used in text?

Pardon my asking, as this is not my specialty:

About the "should" - isn't this language-dependent? For example I recall
that ordinary German print literature barely uses any ligatures at all
these days (ie: I'm not talking about historical texts). And, has anyone
ever attempted to catalogue such ligature practices? (Is this suitable
for CLDR?)

(I also recall being taken aback by the odd look of ligatures in many
LaTeX-typeset English scientific documents, but I suspect that's rather
because some of the commonly used fonts there are lacking in aesthetic
design.)
