The letters representing ‘f’ were prone to corruption, and have caused much scholarly confusion and frustration for various reasons:

It was lost in translation in languages which don’t posses the phonological equivalent of f.
It is similar to f ⋍ v ⋍ wh ⋍ ph and other variants in other languages, some pronunciations unfamiliar to English.

Especially 𓆑 was also associated with forbidden taboos and temporarily erased from hieroglyph inscriptions.
In demotic times scribes went wild in the character.

One clear shift in the reading of the Sanskrit Alphabet is the dangling i which was originally just an ordinary fi and its inverse which was a similar fi

ordinary fi : पि ffi

Both पि And पी should be transcribed as fi and fi, namely fphi and phfi or fi+p and p+fi,
similar to the ph in physics or German Pferd.

There was a global shift from va to a in all alphabets:

Latin atta, Ancient Greek ἄττα (átta), Gothic 𐌰𐍄𐍄𐌰 (atta), Old Church Slavonic отьць (otĭcĭ).

𓇋𓏏𓆑 father (not : attav)

It is not that 𐌰𐍄𐍄𐌰 was orignially pronounced 'atta', it is that the strange orthographic convention
alpha = al'PHA ⋍ V at beginning of words was lost/discarded!

One needs to be careful reading old scripts in similar alphabets with our modern pronounciation!
Other orthographic conventions / lost components were gg⋍ng i<r epsilon<s aa⋍va/ma
