Avestan Fe and the Softening of Stops

Fricatives arising from stops are a regular feature of the Avestan sound system, and the alphabet writes each of them separately from the stop it came from. A script that wrote only the stop would leave a reciter to reconstruct the softening. The shapes come from Pahlavi and the inventory does not. Whoever assembled this alphabet worked from an analysis of the recitation, added signs where the parent hand had none, and ordered the result by place of articulation instead of by the letter sequence that lay behind everything else written in Iran at the time.

Modern editions preserve the distinctions the manuscripts make, including the ones that look redundant, and transliterate them with accents, dots and length marks so that nothing collapses on the page. The apparatus of marks in a scholarly Avestan text is a direct consequence of how many separate signs the alphabet carries. In the digital record the letter is encoded at U+10B1F AVESTAN LETTER FE. The Avestan block sits wholly in the supplementary planes, and every letter in it takes four bytes in the encoding most of the web runs on. That is the practical reason Avestan text is still uncommon online, and why a page carrying it depends on the reader having a font that covers the range. For the community the value of a script that writes every sound is continuity. It makes it possible to check a recitation against a page rather than against another reciter's memory, which is what the alphabet was for and what it still does.
