I always wondered why they didn't put SBL Greek and SBL Hebrew together in the first place. This is lovely, really.
Just wanted to comment that I don't see a glyph for the capital P that represents papyrus in the mss notation, though there is the LXX C, the aleph and bet, the capital R, the symbol for Samaritan, the cursive small-L for lectionaries, etc. It's a really comprehensive font. There is also no notation for consonantal iota, though there is a j-shaped iota that could be used for that.
Thanks for the link, Carl!
