I noticed an odd bug, Scivener seems to “Filter out” certain glyphs from being typed in with a custom keyboard layout, but will still allow them to be pasted in from another program.
The story I am working on involves using a made up alphabet, some obscure letters such as Ꝭ,ꝭ, ẞ and Ᵹ ❪Its worth noting lower-case ß and ᵹ can be typed❫ do not type in scrivener but do work in every other program.
Seems like an odd bug that I thought was worth pointing out.
