Comment 93 for bug 650498

FWIW, we don’t need to limit our comparative research to the relatively few digital typefaces that contained ẞ in 2010. A lot has happened since then!

Myfonts perhaps has the most comprehensive live list of commercially sold fonts with ẞ. See http://www.myfonts.com/search/char:%E1%BA%9E/all/?view=list and change the sample text to something like “MAẞBAND”. The Dresden form appears to be the most popular, even more so among sans-serif typefaces, where the Leipzig form appears to be especially rare. For the left half of the glyph, both rounded (ſ) and angular forms (Γ) are common, on the other hand.

I am not aware of live lists of free fonts that can filter for ẞ, so I quickly rolled my own, for Google fonts:
http://type.dt1.org/1e9e/google/​. As of today, it should contain virtually all Google fonts containing ẞ (however ugly or just plain wrong.) AFAIK, the list also covers most if not all of the ẞ fonts delivered via https://edgewebfonts.adobe.com/fonts​. Fontsquirrel.com has a lot more fonts with ẞ, but I don’t know how to show these without downloading and installing a bunch of web font kits.

Paul et al., what is needed to get the ball rolling? Are you looking for help in drawing glyphs for the various weights etc.?
