You know, Asmus, no analogy is perfect. But mine was a discussion of letters derived from ligatures, and yours is just a random note about shape.

This isn’t really something you can turn into an axiom, much as you would like to. Position in the alphabet may very WIDELY from language to language. As can function. The Latin letter c can mean /k s tʃ ts ʔ ʃ θ/…

Font style isn’t the same thing in this context. The historical letters used to make the 1855 ligatures are *different* letters than those used for the 1859 ligatures.

No, since it’s a question of *spelling*. Some documents use a ligature-letter for the diphthong /juː/. Some documents use two separate letters for the same diphthong. So there’s no “standardized” spelling that works for all text that would be affected here. (Spelling for English wasn’t standardized anyway in historical Deseret texts and there is much variety.)
> Making this an encoding difference would indeed invalidate some documents.
Right now the 1859 characters aren’t representable. Deciding to change the chart glyphs to 1859 glyphs would just destabilize EVERY current Deseret font. That’s not something we should do.

Why? They’re not visually similar to the existing characters. So spoofing wouldn’t be an issue.
