[GNC-dev] [GNC] GnuCash 3.906 Released

[John Ralls]

Font handling in Gtk on MacOS is weird: Pango only calculates the layout for computing box sizes. The actual glyph selection and layout is handled by Cairo, and I don't think it knows how to use CoreText's font substitution. WebKitGtk complicates matters by requiring the FreeType2 Pango backend as well and that does its own font substitution. Regardless, pango is finding the emojis so the test passes. Cairo isn't putting a missing glyph glyph there like I'd expect. I haven't yet figured out why not.

I can think of two avenues to try: Simply forcing have_glyphs to false on MacOS would display the regular letters. Not as pretty but it's sure to work. A bit more difficult and in need of testing would be to use CSS to set the font family for the Association cell to Apple Color Emojis on MacOS.

Regards,
John Ralls

Unfortunately I do not presently have one so I do not know, maybe John might have an idea, the only ideas I have is to set different code points for a paperclip and links for Mac's, disable it for Macs or maybe change the test.
