Hi, I'm out of the Guile scene these days, but, I noticed that the new Unicode hasn't made it into the SRFI-14 character sets. I did the last few charset updates, but, if someone else wants to tackle the Unicode 7.0 update, it is really easy do to. 1. Download http://unicode.org/Public/UNIDATA/UnicodeData.txt 2. Run the unidata_to_charset.pl script that appears in the libguile subdirectory of the software.  This generates srfi-14.i.c.  It requires that you have GNU Indent installed. That's it, really. Regards, Mike Gran
