However, Firefox renders the file with no dashes whatsoever. Instead of dashes, it shows double-width spaces. The HTML renders correctly if lang="de-x-formal" attribute is changed to lang="de". Please note that de-x-formal is a valid language code, as verified with http://schneegans.de/lv/ and it is found in the HTML generated by MediaWiki when the language is set to de-formal. I also noticed that the extra wide spaces Firefox incorrectly shows instead of dashes are in the ori1Uni font while the regular letters are in DejaVu Serif. With lang="de", everything is in DejaVu Serif, including dashes which render correctly. This problem does not occur with Chromium on Ubuntu, nor with Firefox on Debian, nor Firefox on Windows. Ubuntu version: Ubuntu 22.04.2 LTS Firefox version: firefox 111.0-2 from snap Thank you very much for looking into this.
