It would be some work to update our version 19 code to 20. But what I personally don't like is the Unicode support in CMUCL 20. It might be possible to use the non-Unicode version, but I don't know how much that is used or if it even is still provided. Still the networking code would need to updated. The Unicode version has the unfortunate design that a Unicode character may consist of more than one Lisp character - which may break some assumptions in Lisp code. All Unicode implementations have some drawbacks, but the CMUCL design especially makes me not want to use that. :-(

The basis of your dislike is unclear.  Code that assumes Unicode
characters are atomic Lisp characters will break no matter what
the representation of a character is, be it UTF-16 code units or
entire code points encoded in UTF-32.

For better or worse, to reliably process Unicode text one needs to
traffic in strings, not characters.
