Consistency – Typographical Corrector for Gutenberg

The purpose of this plugin is to provide a tool allowing administrators to define typographical rules in order to maintain typographical consistency in the text contents entered on the editor.
The corrections are automatic and are made during the entry as well as on a copy paste.
Autocorrect rules can be enabled/disabled by any user.
Autocorrect is available on pages, posts and custom post types (if their configuration allows Rest API usage)

Currently, the AutoCorrects offered are as follows:

For the English language

• “Straight quote”: Replaces straight quotes with curved quotes

Technically, rules are saved in the wp_options table, while active/inactive states are saved as user meta data.
This data is deleted when the plugin is uninstalled.

Settings are directly in a plugin sidebar under the Block Editor: no more searching for an options page, always available and discreet.
