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?
