Screen Reader Can't Read Note Value in Tempo

Issue type

UI bug

Bug description

When reviewing or editing a tempo mark the screen reader does not announce the note value. With NVDA it simply says nothing for me but I'm told Jaws reports hexadecimal Symbol numbers

Steps to reproduce

1. A score has been set up
2. From the Tempo palette enter, "dotted crotchet = 80" symbol.
   Notice the description given when navigating the palette is good.
3. Use Alt + Left/Right to select the tempo mark in the score in order to edit it.
   Notice that the crotchet and the dot are now not spoken, speech just says "tempo equals 80".
4. Press Enter to edit.
5. Use Arrow Left/Right to navigate across the tempo.
   Notice that speech says "Symbol ECA5" for the crotchet and "symbol ECB7" for the dot. For NVDA says nothing on the music symbols.
   Expected behaviour to read "crotchet" and "dot".

Unicode provides different symbol numbers for musical symbols. Screen reader may need training to recognise some of these, but it would be easier to put a case for standard Unicode values.
