I’ve noticed in the preview window when tying to type in ENERGIĘ the preview is not picking up on E at all (it just show NRGIĘ). Could it be a problem with the Chars list in some way that might be throwing off symbols?
The default font test also fails
Unreal stores fonts internally with UTF-16. Do the chars follow that standard?
Is the extra work worth the effort over just having standard utf ĘĄ symbols, seeing that they exist in parallel already inside of the font? (You could use the same font just a smaller size of text, maybe via rich text)
Not to mention the reduced readability of the text. What special use case is forcing you to adopt this approach?
