This pull request fix the issue that
langattribute are always set to "en" no matter which language the user are using.For YAML metadata tag
lang, according to the document, its default value isen. Since we now override the lang attribute on<html>. I changed it to always set lang toenwhen there is nolangin YAML metadata.Setting up a proper
langattribute is very necceserry for a11y. Since some screen reader like VoiceOver on iOS/macOS will relying on lang attribute to detect content language.Also I fixed a bug where the lang/dir attribute keeps unescaped in HTML exported page. This bug also exists in HackMD.io. Literally, this is a XSS bug but it only run on
file:https:///so I don't think it's critical.Related to Issue: #87
P.S. I'm aware that default lang attribute for notes should be set in the server configuation. But I'd like to keep it in the future discuss now.
