I apologize for not communicating with clarity.  I wanted to "see" the
square in the source code, during debugging, in test failures, and also
in the native UI that s7 feeds at runtime.

In other words, I took "has Unicode" to mean what it normally means
these days , including in Guile or Emacs Lisp, where Unicode "just
works" end-to-end for most practical purposes.  Looking at your
suggestion to hand-craft Unicode byte-vectors, I must have misread "has
Unicode" the way I misread "compatible with R7RS".  :)

I will give those byte-vectors a try.  Thanks!

Thank you!

Rudy
