Nothing to do with fonts or encoding. The problem vanished as soon as
I used 8.6.13, later 8.6.15. It was extended Unicode characters.
 
You can see my discussion here, at the end of the page:
 
https://wiki.tcl-lang.org/page/Unicode

The answer confirmed what I said earlier:

  "8.6 does not support characters above BMP without a little bit of
   hackery"

And you were trying to make use of a 1F4C4 character, which is outside
the BMP.
