Comment 3 for bug 1947424

I don't know about Ubuntu, but FTBFS under a common locale, which would include C, is regarded as a release-critical bug, so there is no "correct" locale, just the one that happens to be standardised across the Debian and Ubuntu buildds (otherwise, would "FTBFS in pbuilder" be a bug in pbuilder? because that's not the "correct" chroot-based build tool).

I don't know if this is the right way to fix it though. I feel like a more general bash associative array in order to set arbitrary environment variables might be the better way to do it, rather than specifically for LANG and LC_ALL.

We probably also should just change the locale in pbuilder-buildpackage to C.UTF-8; we might have some unicode-trashing bugs lurking in pbuilder itself otherwise.
