When you publish a post or update an already published post, this plugin will format the post’s content to certain typographic rules:
<ol>
<li>
All hyphens between two words (surrounded by spaces) will be transformed to m-dashes with the non-breaking spaces ahead of them.
</li>
<li>
All hyphens between digits (without spaces) will be transformed to n-dashes. But it tries to preserve phone numbers.
</li>
<li>
All spaces following these words will be replaced with the non-breaking spaces:
<ul>
<li>at</li>
<li>or </li>
<li>and</li>
<li>the</li>
<li>a</li>
<li>an</li>
<li>in</li>
<li>on</li>
<li>of</li>
<li>for</li>
<li>to</li>
<li>as</li>
<li>i</li>
<li>or</li>
<li>my</li>
</ul>
</li>
<li>
Double and more spaces are replaced with the single ones.
</li>
<li>
All misplaced spaces near dots, colons, semicolons, exclamation marks and question marks are fixed, where possible.
</li>
<li>
Composed words with hyphens in them (e.g. easy-to-use) will be wrapped in <code></code> tags.
</li>
<li>
<code><pre></pre></code> tag and its contents are preserved.
</li>
</ol>
<h4>Problems:</h4>
<ol>
<li>
The plugin will not mess with the HTML tags or other mark-up tags delimited with < and >. It will mess with the Javascript code and such constructions as:
<pre><code> [code]
 bla bla bla
 [/code]
</code></pre>
Though, since version 6, the mess is minimized for [code] and [video] tags.
</li>
<li>
The n-dash thing will mess up with the phone numbers that have only one hyphen in them. They will be confused with the value ranges.
</li>
</ol>

An easy way to self-host all your Google Fonts for increased Privacy or to meet a law requirement. 
Theme and plugin authors are often unwilling to offer a self-hosted method and it’s quite laborious to download and upload each of the required font.
This plugin makes it all easy. It will scan all CSS on your site and automagically download and host on your server the necessary Google Web Fonts.
How it works:
<ul>
<li>Converts all Google Font enqueues to locally hosted CSS files.</li>
<li>Scans and converts any inline style tags using @imports for fonts.</li>
<li>Processes all the local CSS files that weren’t properly enqueued (bad authors?).</li>
<li>While doing so, downloads all the required Google Fonts to your server.</li>
</ul>
Features:
<ul>
<li>Automatic self-hosted fonts with no effort.</li>
<li>Compatible with all themes and plugins.</li>
<li>Supports IE9+ and all modern browsers.</li>
<li>Optimized code benchmarked for performance.</li>
<li>Built-in cache for processing.</li>
<li>Compatible with cache plugins and Autoptimize.</li>
<li>API and hooks for theme & plugin authors.</li>
<li>Uses unicode-range for optimized fonts when using multiple subsets. Google officially does this too, but other solutions for downloading fonts don’t support this.</li>
</ul>
Dev Notes
Cache: The most common reason for a failure. If you have a cache plugin, clear the caches.
It will not work with JS solutions like WebFont Loader. If you’re a developer, you can still use this plugin’s API to get the needed CSS and files to convert your WebFont Loader. I will post instructions on support forums if there’s interest.

Self-Hosted Google Fonts

Automatically self-host all the Google Fonts on your site. Plug and play.
