Locale issues

Inspect the Dockerfile entries referenced around lines 17-18 and 40-41, then build or run the image and check its locale with the locale command. Confirm that a fresh container uses en_US.UTF-8 without manual locale-gen or environment setup; reproduce the reported JSON encoding case to verify the fix.

Locale is not properly set in the docker container

/__w/workspace/workspace/workspaceOS/.bundle/ruby/3.2.0/gems/json-2.9.0/lib/json/common.rb:221:in `encode': "\xC3" on US-ASCII (Encoding::InvalidByteSequenceError)

The locale isn't actually set, so it's POSIX

root@d2baf72eee0d:/var/simdata/openstudio# locale
LANG=
LANGUAGE=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

I have to run

locale-gen en_US en_US.UTF-8
# Either this
update-locale LANG=en_us.UTF-8
# or this
export LANG=en_us.UTF-8

Then it works.

It's possible my setup for the actual test I'm running is different than plain usage, because this still does work

$ docker run -it --rm nrel/openstudio:3.8.0

root@d2baf72eee0d:/var/simdata/openstudio# gem install openstudio-standards
root@d2baf72eee0d:/var/simdata/openstudio# ruby -e "require 'openstudio-standards'"

But the locale should probably be set to en_US.UTF-8 since that was the intent given
