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 <a href="https://github.com/webaxones/consistency/" rel="nofollow ugc">the plugin repository on github</a> 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.
<h3>Technical Informations</h3>
Data Storage: 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 Location: Settings are directly in a plugin sidebar under the Block Editor: no more searching for an options page, always available and discreet.
Supported Locales: The locales supported by this plugin are: 
fr_FR, fr_BE, en_US, en_AU, en_CA, en_NZ, en_ZA, en_GB, de_DE, de_AT, de_CH, ro_RO
If your locale is not supported by Consistency but you still want to access all available rules, you can disable the localization of rules via a filter. Add this to your theme’s functions.php file:
<pre><code>add_filter( 'Consistency\only_show_locale_correction_rules', '__return_false' );
</code></pre>
All correction rules will then appear, with automatic management of rule incompatibilities (if rule A is enabled and it is incompatible with rule B, rule B will be grayed out).

Dashes are punctuation marks that are commonly used in written text. A long dash (—) is known as an em dash, whereas a short dash (–) is known as an en dash.
This plugin converts any whitespace around dashes into smaller hairspaces, to produce a more elegant typographic effect.
Both em and en dashes are recognized.
Look at the following sentence, which uses dashes:
<blockquote>
I love this plugin — and everything about it — because it works so well.
</blockquote>
When this plugin is activated, the sentence would appear like this (with smaller spaces around the dashes):
<blockquote>
I love this plugin — and everything about it — because it works so well.
</blockquote>

Hairspaces Around Dashes

This simple but effective plugin converts spaces around dashes (both em and en dashes) into hairspaces.
