Oh yes definitely. Was always the plan. I was honestly just hoping someone would publish a crate to do that for me.

To be clear, I don't mean publishing a crate to read an environment variable. Of course. I mean a crate that converts a POSIX locale into a Unicode locale.

I guess there's probably a 20% solution that gets 80% of the way there. e.g.,

    $ BTTF_LOCALE="$(echo $LANG | sed 's/_/-/' | sed 's/\..*//')" bttf

If Biff just did that as a stop-gap until the full solution lands, I bet it would work in lots of cases.
