* bug#58328: 28.2; can't select MacOS "System Font" using set-fontset-font

From: Michael Norrish via Bug reports for GNU Emacs, the Swiss army knife of text editors @ 2022-10-06  5:00 UTC (permalink / raw)
  To: 58328

After starting with emacs -q, I paste the following into my *scratch* buffer:

;; ; superscripts and subscripts: ¹²³⁴⁵⁶⁷⁸⁹⁰ ₁₂₃₄₅₆₇₈₉₀ ₘₙₚᵣₛₜₜ
(set-fontset-font t '(#x2070 . #x209C) "System Font" nil 'prepend)

There are subscript characters in the comment line above between U+2070
and U+209C. My default font doesn't render them.  I know that MacOS's
"System Font" is capable of rendering them however. When I do C-x C-e at
the end of the set-fontset-font line, nothing changes in emacs, but I
get numerous repeated messages on the Terminal saying things like

  2022-10-06 15:53:44.239 Emacs-arm64-11[19927:6935256] CoreText note: Client requested name ".SFNS-UltraCompressedLightG4", it will get Times-Roman rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[NSFont systemFontOfSize:].

There is no font named "System Font" on my Mac.  You can use Font Book
to see what fonts you have.  Does it work with one of the fonts shown in
Font Book?

As per the exchange at 

  https://apple.stackexchange.com/questions/431620/how-to-determine-which-font-is-being-used-to-render-a-specific-character-in-term

I am able to paste the subscripts into TextEdit, and when I move my cursor to the relevant character, it tells me that I'm using something called "System Font".

Well, I don't know what TextEdit does, and why.

But you didn't say if Font Book says about which fonts are there.  You
can start Font Book with Spotlight - Command-Space, enter font book, and
return.  Is there a font named "System Font".  If not, Emacs won't be
able to load that font.

If you want to know what font Terminal is using, start Terminal, invoke
Terminal > Preferences from the menu bar, select "Profiles" in the
dialog box, and the "Text" tab on the right side.  There you find it
under "Font".

Both Terminal (and TextEdit) appear to be substituting in another font when the chosen font is not available for the given characters.  In particular, I set my font profile in Terminal to use Inconsolata, but it does not have those subscript characters, so I guess it falls back to the system font (it's pretty obvious that this is happening visually). Various sources indicate that this font (apparently also called San Francisco) is deliberately not available through font-pickers. See, for example,

   apple.stackexchange.com/questions/208849/is-there-a-user-font-for-san-francisco-in-el-capitan

Nonetheless, this used to work, and the error message indicates that whatever code Emacs is using is now deprecated, and that it should be doing something else. I appreciate that special-casing this particular font "name" might be a bit much to ask for.  (In the meantime, I will use DejaVu Sans Mono instead.)

Thanks,
Michael

Can you check if this still occurs with Emacs 29?  I think
this might actually have been cjamged already.

I believe Emacs HEAD can be installed with Homebrew, if you are using
brew.

No further updates within 9 months, so I'm going to assume this is
fixed.  I'm therefore closing this bug report.

If this conclusion is incorrect and this is still an issue, please reply
to this email (use "Reply to all" in your email client) and we can
reopen the bug report.
