Avestan Xve and the Case for Phonetic Care

The rounded velar fricative is one of the sounds most often pointed to when the phonetic care of this alphabet is described. It occupies a letter of its own rather than being written as a fricative followed by a glide. Vowel writing is the innovation that separates this alphabet from everything else written in Iran at the time. The letterforms are Pahlavi and the right to left direction is Pahlavi. The vowels are not: they are full letters, and they come first in the order.

No Avestan manuscript survives from earlier than the thirteenth century of the common era. Every copy in existence is therefore many centuries younger than the alphabet, and the alphabet is many centuries younger again than the words. What reaches a modern edition has passed through both gaps. In the digital record the letter is encoded at U+10B13 AVESTAN LETTER XVE. 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.
