Smart Punctuation on Rendering

Renders ASCII punctuation characters in typographic forms, so you don’t have to struggle to enter desired characters in different editors anymore, for a better reading view.

Limitations

• Live Preview is not supported.
• It may break some elements.
• It may slow down the rendering of a huge note.
• It cannot recognize backslash escaping (e.g. \-\-), since it receives already rendered HTML documents (--). If you really want to avoid character replacements, please use zero-width spaces (-​-).
• It cannot handle complex text because it uses simple regexes and is not aware of AST. Known issues are the following:
  • Element containing a callout is not modified.
  • Element containing a Mermaid diagram is not modified.
  • Element holding links with URI containing specific characters are ignored.

Alternatives

If you want to replace text when you type, consider using another plugin. Of course you can use both plugins: Even the notes you wrote before introducing Smart Typography will be rendered as you wish.

Additionally, your system may have relevant settings as macOS does.
