This is a very nice font and have found some interesting ways of using it during my Descent into Avernus campaign, as well as using it to help make a version of the low infernal language (used by lesser devils and Tieflings).
However, if WotC were to update this font, I would like to see accented characters (such as é, ä, ô, ù, etc) as it currently does not have any of these, as well as maybe support for some uncommon letters such as 'thorn' (þ), 'eth' (ð), or ß.
But this is a minor nitpick over an otherwise excellent and interesting font. Here's hoping they come out with a Celestial version next.
