Have you seen the typographic corrector in your word processor that formats what you type in real time? Well, it's the same idea but with Gutenberg.
This WordPress plugin ensures consistent typography and punctuation on your site.
Corrections are applied automatically both during text entry and when pasting text.
All users can choose to enable or disable corrections, but only administrators can configure the correction rules.
Autocorrect is available for pages, posts, and custom post types (if they are configured to use the Rest API).
The available automatic corrections are listed on
the plugin repository on github and are categorized as follows: Apostrophes, Quotation Marks, Dashes, Suffixes, Spaces, Case, Ellipsis, Symbols.
Pressing Ctrl+Z or Cmd+Z immediately after a correction disables the correction for the next keystroke.
