SHELL text encoding OS X?

[hh]

Hi Klaus, in a first step this depends more on your system settings than on LC.

In Terminal (or via shell use) this.

prints all environment vars: locale
current encoding: locale charmap
available locales: locale -a
available encodings: locale -m

Works on MacOS X and Linux. (On Win I don't know how to get from CLI, you have to find locale.txt or locale.xml?)
How to adjust "shell" according to that you certainly know better than I do.
