Hi all,

from time to time we get invisible characters into our source code,  
leading to strange compiler errors. It's really hard to spot those  
blank one-pixel-wide glyphs.

Truetype fonts have a hollow rectangle to indicate missing glyphs.  
This package patches the StrikeFonts to show a similar hollow  
rectangle for any non-whitespace character that had a blank glyph:

Tested in 3.8 and 3.9, should work in virtually any version.

See attached image for the result.
