> “UnicodeMath,” described in https://www.unicode.org/notes/tn28/ , might be an interesting solution. The plain-text representation is fairly readable, and something that is not ad hoc, but actually discussed and agreed upon by a panel of mathematicians. It could be copied and pasted from the terminal or text editor to a UnicodeMath-enabled processor (if you can find one) for real formatting.

Do you know any editor that implements that TN?
