Is there a recommended notation for transcription? I have seen various styles of punctuation to indicate such things as uncertain characters, clarifications or suggested interpretations, inserted text, marginalia, underlined text, italics, struck-out text, and even the use of different colours by the original author. Some of these are incomplete -- in my opinion -- and some rely on special symbols that are hard to generate reliably (e.g. the Unicode symbols U+202A and U+202B for L-to-R and R-to-L embedding).
The same applies to line numbering (how often, which margin, etc). and paragraphing numbering.
I could pick any one of the schemes but I just wondered if there was a recommended style.
