How this works
Each entry line contains links to the possible icons in that series. Because many of the 'possible' codes may not actually exist - either because they are not logical/required or because no-one has yet needed to create them - this would cause lots of 'missing image' errors. CSS is therefore used to suppress those icons which do not exist, which is why these pages won't work effectively on non- CSS-capable browsers or for screen readers. It is, however, far more complete than the main manually-maintained version.

The purpose of these tables is to 'find' what icons already exist within WP, and to make it easier for editors to locate the simplest icon for their purpose. Because of this 'consolidation' approach you will find some icons are actually "wrong" according to some editors as their codes might be in error in some way. Similarly, it is often easier to overlay one simple icon with another simple icon to produce the required complexity, rather than create another icon from scratch. This also means that the tables shouldn't be used as a guide to what needs creating; just because there is a blank position it doesn't have to be filled!

''It helps a lot to use this table on a wide-screen display! Multi-line-types in a single icon are being moved to their own tables due to the extension of the number of prefixes (eg 'h')''
