Thanks Marc and Lassi. I will take a look at Gambit's implementation. In that same direction, I also adapted Alex Shin's iset library which he used to support unicode in his utf8 egg for Chicken Scheme.

It has been checked against Racket (there are a few differences that seem to be due to differences in how “numeric characters” are defined in R6RS and R7RS specs). The implementation creates all the data structures by analyzing the Unicode database files. These files are the main ones implementing SRFI 14: https://github.com/gambit/gambit/blob/master/lib/gambit/char/char%23.scm https://github.com/gambit/gambit/blob/master/lib/gambit/char/char.scm Marc Feeley
