Formatting component

The Formatting component primarily consists of formatting.php in wp-includes. This file contains various escaping and sanitization functions, and other functions for both security and formatting text. This includes two infamous functions with storied WordPress histories, wpautop() and wptexturize(). Formatting also includes kses.php, WordPress’s HTML security filter.

Changes to the Formatting functions generally require extensive unit testing and a consensus of lead developers.  This tends to happen with deliberation across two or more versions.  The easiest way to contribute to this component is to write bug reports or unit tests for existing code.  Remember, all security matters should be reported according to the Security FAQ and are not part of the public Formatting information.

Projects for the 4.4 milestone will focus on supporting the Shortcode API Roadmap, which is deeply entwined with almost every facet of the Formatting functions. Large changes and many bug fixes are needed, and in some ways will also be made possible by the Shortcode plans.

Subcomponents: Emoji, Shortcodes, and Charset.
