Certainly on topic, though independent of Unicode.

There's been at least D, F, J, K (APL family), R, S (_before_ R), T (a Lisp), X (the window system), Z (some specification language). Any single-letter non-ASCII names yet? Spelled-out like Lambda and Omega don't count. -- https://mail.python.org/mailman/listinfo/python-list
