I'll bet you have a font corruption problem.

1. Split the uninstalled fonts into two groups.
2. Import the first group.
3. Check to see if they imported successfully.
   • If yes, you know the problem is in the second group, so go to step #1.
   • If no, the second group might be okay, so try importing that.

And so on.

You should be able to narrow down the problem without having to import each font one at a time. But my guess is that one or more of your fonts is corrupted.

(The links to the Musica typeface don't seem to lead anywhere useful.)

Uptake of the Musical Symbols in Unicode has been very limited: there were already fonts that allowed music symbols to be incorporated into text blocks, such as the Bach Musicological Font (which is now hard to find); and notation applications use their own fonts, whose symbols tend to use the 'ASCII' glyph range.

However, over the last few years, a standard for music notation symbols in Unicode has been formulated, called SMuFL. SMUFL-compliant fonts will also include glyphs in the Unicode reserved locations that you are after.

The SMuFL reference font, Bravura, comes in two versions, one for notation software, and the other, Bravura Text, for use in text. Either of these will include the characters you want. You can download the fonts here.
