openmcl handles utf8 decently › Steve Jenson's blog

I tested openmcl recently to see if it can store and print UTF-8 without harming it. Worked like a charm. You can most likely attribute this to CLHS 13.1.3 that says a character is a non-negative integer. In Lisp, an integer has no upper bound.

testing-utf8.lisp:


    (defvar *utf8* "𐌸𐌹𐌶𐌰𐌹: 𐍅𐌿𐌻𐍆𐌹𐌻𐌰")

    (format t "~A" *utf8*)


    $ openmcl -l testing-utf8.lisp

    ; loading system definition from

    ; /Users/stevej/.openmcl/asdf-install/asdf-install.asd into #<Package "ASDF0">

    ; registering #<SYSTEM ASDF-INSTALL #x63BD006> as ASDF-INSTALL

Awesome!
