Issues with time signature parentheses glyphs in Emmentaler and Gonville
While working on the time signatures code, I found out that Emmentaler (mscore) and Gonville (gootville) have some problems with their time signature parentheses glyphs, codes xE094 and xE095.
In Emmentaler, the large timeSigParensLeft (xE094) and timeSigParensRight (xE095) symbols have too narrow bounding boxes so they overlap other glyphs.
In Gonville, these two glyphs are similar to the smaller version glyphs timeSigParensLeftSmall (xE092) and timeSigParensRightSmall (xE093), so the font doesn't really have large parentheses glyphs, nor are they replaced by the fallback font Bravura.
The image below shows the four parenthetical glyphs in Bravura, Emmentaler and Gonville (left to right).
I am not sure how do we fix this kind of problems. Can the fonts and metadata files be modified by MuseScore developers?
