6 years ago @dscorbett This should be reported to Unicode as well since it currently states that an isolated rohingya yeh does not occur:
- in table 9-9 "Right-Joining Arabic Characters" where it is noted "Isolated form does not occur."
- in table 9-10 "Forms of the Arabic Letter yeh" where no xn is shown.
- in the following paragraph on page 384
U+08AC ARABIC LETTER ROHINGYA YEH is used in the Arabic orthography for the Rohingya language of Myanmar. It represents a medial ya, corresponding to the use of U+103B MYANMAR CONSONANT SIGN MEDIAL YA in the Myanmar script. It is a right-joining letter, but never occurs in isolated form. It only occurs after certain consonants, forming a conjunct letter with those consonants.

Issue
The Noto Arabic fonts use the same glyph for the isolated and final forms of U+08AC ARABIC LETTER ROHINGYA YEH, probably because this letter never appears in isolated form in Rohingya text. It does, however, appear in isolated form when discussing the letter itself. In the two sources I have found (Rohingya Text Book I, p. 64 and L2/10-288R), the left appendage of the final form curves down, whereas in the isolated form it curves up (or at least not down). If this is the usual pattern in Rohingya, and not a handwritten mistake copied into the textbook’s computer font, then Noto’s glyphs need changing.
