The rectangles instead of glyphs bug in Preview only occurs with 
OpenType/CFF fonts. If you are seeing this problem with TrueType fonts 
it is because the TrueType subsetting has failed and a CFF fallback font 
has been embedded.

I previously described how the PDF embedded font typed can be checked here:


There is probably a bug in the TrueType subsetting somewhere as it 
should not be failing on fonts that FreeType can display. However I am 
unable to fix this unless I can reproduce the problem on Linux or 
someone on a Mac can find find out which line in cairo-truetype-subset.c
