Add an admin widget labeled “HTML Special Characters” that is present in the admin Add/Edit Post and Add/Edit Page pages. Clicking on any special character in the widget causes its character encoding to be inserted into the post body text field at the current cursor location (or at the end of the post if the cursor isn’t located in the post body field). Hovering over any of the special characters in the admin widget causes hover text to appear that shows the HTML entity encoding for the character as well as the name of the character.

Note that when used in the visual editor mode the special character itself is added to the post body. Also note that the visual editor has its own special characters popup helper accessible via the advanced toolbar, which depending on your usage, may make this plugin unnecessary for you. In truth, the plugin is intended more for the non-visual (aka HTML) mode as that is the mode I (the plugin author) use.

Filters

The plugin exposes two filters for hooking. Typically, code making use of filters should ideally be put into a mu-plugin or site-specific plugin (which is beyond the scope of this readme to explain).

c2c_html_special_characters (filter)

The ‘c2c_html_special_characters’ hook allows you to remove existing characters or entire groups of characters, and/or add new characters or groups of characters.

Arguments:

$codes (array) : An association array in which the keys are a grouping name and the values are associative arrays themselves with the code as the key and the human-friendly descriptions as the values.

Example:

/**\n * Add a new grouping of characters (accented 'A's).\n *\n * @param array $characters Default HTML special characters.\n * @return array\n */\nfunction more_html_special_characters( $characters ) {\n    $characters['accented_a'] = array(\n        'name'     => 'Accented A',\n        '&Agrave;' => 'A grave accent',\n        '&Aacute;' => 'A accute accent',\n        '&Acirc;'  => 'A circumflex',\n        '&Atilde;' => 'A tilde',\n        '&Auml;'   => 'A umlaut',\n        '&Aring;'  => 'A ring',\n        '&AElig;'  => 'AE ligature',\n    );\n    return $characters; // Important!\n}\nadd_filter( 'c2c_html_special_characters', 'more_html_special_characters' );\n

c2c_html_special_characters_post_type (filter)

The ‘c2c_html_special_characters_post_type’ hook allows you to specify which post_types for which the HTML Special Characters metabox should be shown.

Arguments:

$post_types (array) : An array of post types. By default, this value is array( 'page', 'post' )

Example:

/**\n * Show HTML Special Characters Helper for additional post_types.\n *\n * @param array $post_types Arry of post types.\n * @return array\n */\nfunction more_html_special_characters_post_types( $post_types ) {\n    $post_types[] = 'products'; // Show for products\n    unset( $post_types['page'] ); // Don't show for pages\n    return $post_types;\n}\nadd_filter( 'c2c_html_special_characters_post_types', 'more_html_special_characters_post_types' );\n

\n","installation":"

Install via the built-in WordPress plugin installer. Or download and unzip html-special-characters-helper.zip inside the plugins directory for your site (typically wp-content/plugins/)
Activate the plugin through the ‘Plugins’ admin menu in WordPress
An admin widget entitled “HTML Special Characters” will now be present in your write post and write page forms. Simply click on any character that you would like inserted into your post.

Installation Instructions

Install via the built-in WordPress plugin installer. Or download and unzip html-special-characters-helper.zip inside the plugins directory for your site (typically wp-content/plugins/)
Activate the plugin through the ‘Plugins’ admin menu in WordPress
An admin widget entitled “HTML Special Characters” will now be present in your write post and write page forms. Simply click on any character that you would like inserted into your post.

How do I use the “HTML Special Characters” admin widget to insert special characters into other post fields (such as the post title)?

You can’t. The plugin only inserts the HTML character encodings into the post body. However, you can certainly hover over the character you want to use to see the HTML encoding for it (it’ll start with an ampersand, &, and end with a semi-color, ;) and type that into the field.

I’ve activated the plugin and don’t see the “HTML Special Characters” admin widget when I go to write a post; where is it?

Refer to the screenshots to get an idea of what the helper widget looks like. You should find the widget in the right sidebar of the admin page when creating or editing a post, most likely at the bottom of the sidebar. It’s possible it may have been dragged to someplace below the textarea where you provide the post’s content.

If you still can’t find it, look to the upper-right of the page for a “Screen Options” link that reveals a panel of options. In the “Boxes” section, ensure the checkbox for “HTML Special Characters” is checked.
