Hi, I'm getting this behavior: $ gsi Gambit v4.7.2
#\à *** ERROR IN (console)@1.1 -- Invalid '#\' name: "\303\240"
is that a misconfiguration on my part somehow? Marijn
Yes, you need to -:t8 for Gambit terminal IO to go UTF8, see docs. 2014-05-16 13:06 GMT+02:00 Marijn Schouten (hkBst) <hkbst@gentoo.org>:

This comment makes me wonder if ISO-8859-1 is the right default for ttys. Perhaps it would be less surprising if UTF-8 was the default. Does anyone know of a way to autodetect the tty’s character encoding? It would be nice if xterm could be forced to send a BOM so that Gambit would autodetect the character encoding (if ttys were started with the ___CHAR_ENCODING_UTF_FALLBACK_ISO_8859_1 character encoding mode). But I see no way of doing this after a quick look at xterm’s source code. There is a certain consistency in using ISO-8859-1 as the default for all I/O ports, so that may still be the “least surprising” default. Thougths about this?

There's always the environment variable LANG. On my machine env tell me LANG=en_CA.utf8 and the .utf8 on the en_CA clues me in. -- hendrik

Is there a simple way to parse the LANG environment variable to determine the preferred character encoding? Marc

Last time I looked at the list of languages for Debian (I think that was in the installer somewhere) just about every language appeared in two forms -- one with the suffix utf8 anen one without it, So I'd guess it would be useful to just test whether the LANG variable ended with utf8. There might be exceptions to this, but if so we could wait to hear abbout them. -- hendrik
Can't the LANG variable be of quite arbitrary content also. It would be of value for the Gambit code to be able to know the max Unicode char it can output just as not to run into IO exceptions .. or wait, the ISO-8859-1 does not map to a linear sequence of Unicode chars, or how is it? - anyhow how avoid? 2014-05-16 15:45 GMT+02:00 Hendrik Boom <hendrik@topoi.pooq.com>:
