[Interest] Missing glyphs using Qt 5(.3+?) on Macintosh

I noticed today that when I build my application using Qt 5.4 from the dev branch and I try to display certain mathematical symbols (say, in a QPlainTextEdit), I get the empty square box glyph instead of the correct symbol glyph. When I build using Qt 4.8.6, I get the correct symbols displayed. I

I've noticed that compiling my application takes considerably longer when compiling using Qt5 vs. Qt 4. This is true on Macintosh 10.9 and Windows 7. I'm comparing builds done using the same machine with the same application source code. For example, Macintosh: Qt 4.8.6: Elapsed time: 06:20 Qt 5.4

Since updating my git checkout of Qt 5.3 a few days ago to the release branch (I was previously using the stable branch as of early April) and rebuilding Qt, I noticed that I sometimes get weird text drawing problems in my application on Mac OSX 10.9.2 but not Windows 7. If I compile my applicatio
