Hi Ciarán,

Thanks for a well-written bugreport!

Upstream collection of Noto font files include some available both 
hinted and unhinted, and my packaging routines for Debian simply skips 
the unhinted files where both hinted and unhinted exists, by the 
assumptions that the unhinted files contain no additional information 
but are only slimmed down versions of the hinted ones.  Maybe that 
assumpltion is wrong.

Since you mention previously using unhinted fonts, could you please try 
fetch the current _unhinted_ fonts from upstream and check if the 
symbols are missing there as well?  If so, then we should maybe consider 
packaging the unhinted fonts too.
