The pointer, for those whose eyes are imperfect, like mine, is off by 
one.  The problem is the codepoint 8216 inverted quote ‘, not the 
following underscore _ codepoint 95.  Remove the _ and the error 
persists, with the pointer pointing to ‘.  Ampersand @ 64 is also 
invalid, but the error persists with that removed.

Right.  Turning ' to ‘ is a common evil of bad clients.
