Orkhon alphabet
From FirespeakerWiki
* Both Phoenician/Aramaic and Brahmi had three voiceless sibilants, but because the alphabetical ordering was lost, the correspondences among them are not clear.
Not accounted for are the six Brahmi consonants File:Brahmi bh.svg bh, File:Brahmi gh.svg gh, File:Brahmi h.svg h, File:Brahmi j.svg j, File:Brahmi jh.svg jh, File:Brahmi ny.svg ny, some of which could conceivably derive from the three Aramaic consonants with no obvious correspondence, he, heth, and ayin. (Brahmi File:Brahmi ng.svg ng was a later development.)
