List of glyphs (codepoint and glyph names) for NotoSansSymbols-Regular none

Description Michael Katzmann 2024-01-23 23:47:08 UTC 
google-noto-fonts package installs configuration files - 
/etc/fonts/conf.d/58-google-noto-sans-symbols2.conf
and
/etc/fonts/conf.d/58-google-noto-sans-symbols-vf.conf

which cause Postscript platform font /Symbol to use NotoSansSymbols[wght].ttf
# fc-match Symbol
NotoSansSymbols[wght].ttf: "Noto Sans Symbols" "Regular"

This font does not have the glyphs required for the standard platform font "Symbol" https://en.wikipedia.org/wiki/Symbol_(typeface)
This should not hijack /Symbol name ... the correct file could be StandardSymbolsPS.t1.

This results in PDF files that use the Symbol font to produce no or wrong characters for the glyphs (example /Omega or /degree (see PDF file https://drive.google.com/file/d/1SrcMEFqI26un4MAxh2OHdoTbOi9hgM4v).
This file renders correctly using browsers (Chrome Firefox or Ghostscript) because they include Postscript core fonts but evince, okular, atril rely on Fedora to provide fonts. These applications do not render the symbol glyphs

Reproducible: Always

Steps to Reproduce:
view PDF with symbol glyphs from Postscript standard symbol font
Actual Results:  
no symbol glyphs shown for PDF viewers using Fedora fonts (rather than built in Postscript core fonts)

I can reproduce in a Rawhide Live image (though not in my SB39 host).
