Avestan Bhe and a Sound No Semitic Letter Covered

The bilabial fricative is a sound a script inheriting only Semitic letters would have had no provision for. It has one here because the alphabet was built to a phonetic inventory rather than to a borrowed letter list. The gap between the words and the writing is the central fact about this alphabet, and it runs in both directions. The Avesta is far older than the script, and every surviving manuscript is far younger, so the script sits between two long stretches of transmission and belongs wholly to neither.

The Zoroastrian communities that carried these manuscripts, in Iran and in western India, are small, and the copying was sustained by priestly families rather than by any large institution. That the texts survive at all is a consequence of that continuity. In the digital record the letter is encoded at U+10B21 AVESTAN LETTER BHE. The whole Avestan block lies above the Basic Multilingual Plane, so each character needs a surrogate pair in the encodings that use them, and a font carrying the script is required before anything appears on a screen at all. What this alphabet holds is a performance. The atlas describes it and does not instruct in it: the recitation belongs to the community that maintains it, and the interest here is in what the script was built to do and how well it did it.
