Re: Encoding translation error on macOS Sonoma 14.2

Not surprisingly, installing vile via Homebrew produces the same results.

Hi Thomas,

Thanks for your reply. I was hoping that would work, but no luck so far:

$ LC_ALL=en_US.UTF-8 vile

Cannot setup translation from  to UTF-8

It seems odd that vl_narrow_enc.encoding is empty in the error message above.

For locale, I see the same as you:

$ locale -a | wc -l
     203

Output of locale:

$ locale

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=

However, as I showed above, even explicitly setting LC_ALL has no effect:

$ export LC_ALL="en_US.UTF-8"
$ locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

hmm - I've 3 macs that I intend upgrading to Sonoma, but as usual put it off.
One is an M2 (the others are Intel).  Those are all on Ventura, and locales work.

"locale -a |wc -l" lists 203 settings.

What does "locale" print for your environment?
The message indicates that there's no locale set.

If Apple's lobotomized locale support, you might just as well set

    LC_ALL=en_US.UTF-8

(that would probably even work with something like OpenBSD).
