I have made Bigloo adaptions of SRFI 13 - String Libraries <https://github.com/donaldsonjw/srf13>and SRFI 14-Character Sets <https://github.com/donaldsonjw/srfi14>. As with the sample implementations, they are limited to iso-latin 1 but hopefully will still be useful to some.
Thank you. These are among the most useful and widely used SRFIs.
Marc Feeley and John Cowan can advise how to implement SRFI 14 for the full Unicode range. Marc designed a simple and efficient data structure for encoding subsets of the Unicode character set. I don't know whether it has been incorporated into Gambit yet.
