HTML Special Characters Helper v1.6

I’d like to announce the official release of the updated HTML Special Characters Helper plugin (v1.6) for WordPress.

Admin widget on the Write Post page for inserting HTML encodings of special characters into the post.

Recommended major compatibility update. Highlights: JS/CSS handling tweaks; misc non-functionality tweaks; noted compatibility with WP 3.0+.

For more details, instructions, screenshots, and the download link, visit the plugin’s official homepage at :

Comments welcome on this post for this version of the plugin. Comments will be closed once this release has been superseded by another.

Detailed ChangeLog

These are the detailed changes, which may or may not make sense to you depending on your familiarity with the previous features and internals of the plugin.

  • Extract all inline JavaScript into add_admin_js() and output via admin_print_footer_scripts action
  • Extract all inline CSS into add_admin_css()
  • Only output CSS on the add/edit post/page pages
  • Remove all references to $for (which was context variable that lingered from former rte popup)
  • Remove JavaScript related to inserting text into editor and just use send_to_editor()
  • Change the ‘Toggle more?’ link to ‘See more’/’See less’ (JavaScript toggles between the two as appropriate)
  • Move hooking of actions out of constructor and into class’s admin_init()
  • Rename add_css() to add_admin_css()
  • Assign object instance to global variable, $c2c_html_special_characters_helper, to allow for external manipulation
  • Rename class from ‘HTMLSpecialCharactersHelper’ to ‘c2c_HTMLSpecialCharactersHelper’
  • Don’t define class unless within admin section
  • Note compatibility with WP 3.0+
  • Minor code reformatting (spacing)
  • Remove documentation and instructions from top of plugin file (all of that and more are contained in readme.txt)
  • Add PHPDoc documentation
  • Add package info to top of file
  • Update copyright date
  • Add Upgrade Notice section to readme.txt

I sometimes need Danish and Icelandic special national characters, so an opportunity to add your own, would be a nice option.

Anyway it’s still a great plugin you made 🙂


Will this special-characters plug-in handle the extended Greek characters shown on WP will display these in WYSIWYG when I enter HTML equivalents in the WP HTML editor. For example, the sequence ἀρχή displays identical to this small image: But when I save the draft, it usually turns each character into a question mark.

Since I’m new to WP, any help would be appreciated!
