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>

This plugin appears at Settings -> Fonts.
For each @font-face, specify .woff URL, weight, style, and a font family name.
Appropriate @font-face rules will be saved to a CSS file and enqueued with wp_enqueue_stylesheet, so that you can use the font with the font-family CSS property.
No nonsense. No API keys. No font conversion. No bloat.
<h4>Integration Instructions for Plugin & Theme Developers</h4>
Use ECF_Plugin::get_font_families() to get a list of font families added with Elegant Custom Fonts. Then add these to any “Font” dropdowns in your plugin or theme.
Example:
if (class_exists(‘ECF_Plugin’)) { 
 $font_family_list = ECF_Plugin::get_font_families(); 
} else { 
 $font_family_list = null; 
}
/* loop through the $font_family_list array and add each family to your ‘Font’ dropdowns */

Elegant Custom Fonts

A simple solution for self-hosted custom fonts.
