Well there is a background document for future consideration: https://www.unicode.org/L2/L2020/20290-cistercian-digits.pdf

However, it says:

> It is not clear that there is any current need for Unicode support. Western Michigan University’s Medieval Institute (Cistercian and Monastic Studies) has a digitization project of Cistercian mss, but as of end 2020 they have not expressed any desire for computer encoding of the numerals. This document is therefore background information so that work is not duplicated if a need arises later.
