Usually the language of PDF.js is the same as the language of your browser. If you want to change it manually, there is a PDFJS.locale preference that you can set. Note that #4956 disabled most of the hash parameters for non-development builds, so it should be done using preferences.

@Snuffleupagus Perhaps we would also need to update the wiki at https://github.com/mozilla/pdf.js/wiki/Viewer-options to avoid confusion? I'll leave that to you to decide as you have also made that PR and know about the details.

Closing as answered.

I moved the relevant options to https://github.com/mozilla/pdf.js/wiki/Debugging-pdf.js, since that is where they belong now that they are disabled by default in production builds.
@timvandermeij Thanks for the pointer, I completely forgot that we should update those pages!
