The base-char issue again...

Hi all,

I'm having a regression of a recurring issue with unicode characters, 
which I've fixed in other parts of my code base, but now I'm having the 
darnest time trying to write some unicode to a text file, and after 
reviewing the mailing list and my other file access, I can't figure out 
what the issue is.  It must be something obvious I'm missing... can 
anyone see what I'm doing wrong below.  I've got the default char 
element type set in .lispworks.  This is on macOS 8.1.0 ( I haven't 
upgraded to 8.1.1 yet, but I didn't see anything liek this in the 
release notes). Just trying to include unicode chat 0x2019.

Cheers,
Steve
