How to insert music symbols into Preview app? Not all installed fonts available.

Yes, I discovered that works and was writing the following when your reply arrived!

I still can't enter a character using the Option key with the Unicode keyboard, but I found the solution here

<https://apple.stackexchange.com/questions/183045/how-can-i-type-unicode-characters-without-using-the-mouse#183056>

that you contributed to. I entered "u+1d15e" into the search field in 𝅥Character Viewer in collapsed Emoji view. After selecting the symbol with a down arrow or the mouse, a single click inserted it into the underlying text input field. Sometimes the Character Viewer closes, sometimes it doesn't...

In Character Viewer expanded/full view (toggled by the icon to the right of the search field, as you know, but for others' info), I can search for either "u+1d15e" or "1d15e", but I have to double click on the found symbol for it to appear in an underlying text field. Without searching, I can also double click on any symbol displayed in the center panel to insert it into a document.

In my previous unsuccessful attempts, in Character Viewer full view, I selected a symbol with a single click, then single and double clicked the enlarged symbol in the right side info panel, which did nothing. Now I know I can double click on a smaller character in the center panel to insert it. 𝅗𝅥𝅗𝅥𝅗𝅥𝅗𝅥𝅗𝅥𝅗𝅥

Thanks for your help!

I installed Bravura, and I got Font Book to display the glyph by hovering the cursor over a character. I attempted to enter Option E1D3 (Bravura half-note Glyph 437 = U+E1D3) but a question mark in a square is displayed in both a Preview.app Text box and in Pages.

I cannot enter a code longer than 4 digits in Text Edit or Pages or Preview. I see the half note character in Character Viewer, but Option 1D15E truncates to the 1D15 character, LATIN LETTER SMALL CAPITAL OU:

Thanks, but I do have Opus, also PC Music Font, activated and validated by Font Book.

I just got Pages to display half-note characters dragged from both Opus and PC Music Font. In Pages I then opened all fonts (Format>Fonts>Show Fonts) and selected Opus and PC Music Font; those fonts are now choices added to the top of the Text > Font menu.

In Preview, a half-note dragged from Opus into a Text box looks like this: �

A half-note dragged from PC Music Font into a Text box in Preview looks like this: h

I need a way to get Preview to read/recognize all the Computer fonts. I searched unsuccessfully for "font" in the info.plist inside Preview.app package contents, no hits.

I don't know how the fonts code the characters, I can't find a way to read that info on the Mac. In Pages, when I type a small h the Opus font and the PC Music Font display half notes, slightly different from each other.

I want to enter half notes and several other music symbols into Preview. I want to know how to enable additional fonts such as Opus or PC Music in Preview, or how to directly enter Unicode Supplementary Multilingual Plane characters in the range U+10000 to U+1FFFF <https://codepoints.net/supplementary_multilingual_plane> such as half note symbol U+1D15E. As mentioned above, attempting to enter U+1D15E by holding Option key and typing 1D15E (using the Unicode Hex Input keyboard) truncates to 1D15, the character "ᴕ". Copying the half note character to Preview.app or to here displays "h".

I don't know how to enter that code, it's a similar problem: it gets truncated to 4 digits, as did the 5 digit code 1D15E. When attempting to enter d834dd5e while holding Option key (using the Unicode Hex Input keyboard), it truncates to d834, a character I don't recognize and can't reproduce here. If I type Option d834dd5e here, it again truncates after four digits d834 but displays the character �

I have Symbola font but lots of characters do not display in Font Book. Font Book doesn't seem to give any indication what code is associated with each glyph so I don't know which code ranges don't display, but I saw no music characters while paging through them all. I cannot enter more than 4 characters with the Unicode Hex Input mapping using the Option key.
