As part of #PalaeographySchool23, we'll be using the MUFI Unicode specifications for transcription. I've created a spreadsheet of the codes, divided by category, which will be added to by the students. If others will find this useful, I can make it publicly available at the end.
The file does not yet have a complete selection of codes/signs (e.g. I still need to add all the p and q variants), but this may be useful to some of you. If you send me additional codes, I can update and put this up again in October.
Please note you need to install a font like Junicode in order to be able to see all the signs!
