[Indic-texts] encoding/transcribing the bhale symbol

Hi all, Just wondering if anyone has been encoding/transcribing the bhale symbol, and how you represent it. It doesn't seem to have made it into Unicode yet. As a follow-up to that, I was wondering if it was possible to set up a section of IndicTexts TEIWiki to document encoding/transcribing practices in current and past projects. I've thought a few times about putting together a document that just lists the different ways people have transcribed pṛṣṭhamātrās, virāmas, etc. that isn't covered in any specification. Best, Charles
