Cygwin is a sort of *nix implementation that runs in Windows.  I believe 
it's picking up the system fonts, which in this case are the installed 
Windows fonts plus any extra fonts specified in /etc/fonts/local.conf.  
The problem occurred at the Windows level: both versions of the 
CharisSIL font were _installed_.  I believe this happened because of the 
file name change at some point: the older font files had names like 
CharisSIL-R.ttf, and the newer ones had names like CharisSILR.ttf (or 
something like that--I'm not on that computer now).  So Windows happily 
installed both versions of this font in C:\Windows\Fonts\, because the 
two versions had different file names.
