only a few Hex symbols recognized in Mac OSx Pages?
Well, you need a font that actually contains all the glyphs.
Which most &quot;generic&quot; fonts (for writing text) probably won't.
The term to search for such fonts is SMuFL. This is standard initiated by Steinberg (and now developed by W3C) to bring music notation fonts to the Unicode era.
The open source &quot;Bravura&quot; font is available in OTF format for Mac at: https://github.com/steinbergmedia/bravura/tree/master/redist/otf
Btw. you don't need to enter the Unicode glyph codes into the Character Viewer search bar. The glyph name, e.g. &quot;Segno&quot;, will do as well.
There are some more SMuFL fonts contained in the demo version of Steinbergs Dorico music notation software available at: https://www.steinberg.net/en/products/steinberg_trial_versions/dorico.html
