Oops, I happen to have an esperanto locale on my system, and berlin probably has one too. That would explain why I was able to build the website, and why the website is updated.

This is how I defined that locale: https://git.lepiller.eu/system-configuration/tree/-/modules/config/os.scm#L117

Weirdly, glibc-locales provides "eo" but not "eo.utf8"
