ValueError: unknown locale: UTF-8

I get the following error when executing mkdocs build while pdf-export is enabled.

For reproduction: I used the https://github.com/squidfunk/mkdocs-material Repro for testing purposes.

Can you post the output of locale please? It seems like your locales are messed up... UTF-8 is definitely not a valid locale.

What version of MacOS are you running? What are your language settings?

[lukasreussner]

Just fixed the local.

➜ mkdocs-material-master locale LANG= 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"

However, now I'm getting this error:

The reason for this is that this repository is actually setting the theme to null and using the custom_dir option instead. This makes sense for the material theme repo, since it obviously uses itself as the theme.

For this case, I'll have to fallback to the generic renderer. This will however break the PDF export for this repository, since it requires the material theme stylesheet I provide to work.

At this point it's probably best to just switch to your own repository for further testing.

[lukasreussner]

Changing the repository and setting the theme doesn't solve the problem. Just tried it and got the same error when executing mkdocs build:

That was my mkdocs.yml:

`site_name: My Docs nav:

• About: index.md theme: material`

[shauser]

I fixed an issue when the enabled_if_env option is not set. Can you please re-test with v0.2.2? It should be up on pypi in about 5 minutes.

The exception above looks like the theme is still unset though, so if you get the same exception, please make sure you have a theme set.

[shauser]

And handling for empty theme should also be fixed.
