Re: Invalid shell assignments in environment

[Glenn Fowler <gsf@xxxxxxxxxxxxxxxx>]

what about this scenario

in UTF-8 locale parent shell:
glück=bad
export glück
run child shell in C locale:
        run grandchild shell in UTF-8 locale
                echo $glück

if the child shell only passes valid environment variables
then it will eliminate glück from the environment because
it contains non-identifier characters
so $glück will be undefined in the grandchild
(if the UTF-8 encoding of u-umlaut doesn't trigger non-identifier,
 then there will be some other char whose unicode encoding will)

this would seem to be an argument for the shell
ignoring but passing on non-shell-identifers in the environment

a stickier point is what happens if a UTF-8 locale
is set midway in the child shell -- does it have any $glück ?
