Character Entities Editor

This editor is available from the Entities tab of the Configuration Editor.

This is where you can add and delete character entities. Character entities are used to display special characters such as the less-than and greater-than characters that are used to contain tags (the hypertext markup language). In addition, they are also used to display characters that are not available in the lower ASCII set, but are in the ISO-Latin-1 character set or other character set.

List Boxes

Character entities - Contains a list of all character entities, including "built-in entities" that validate all numeric character entities (such as ") and certain groups of named entities. See below for the buttons used to add and delete character entities to and from this list box.

(HTML 2.0 entities) - Named entities valid for HTML 2.0 compliant documents. Included are the popular character entities >, <, ", and many more.
(math, greek entities) - Named entities that include mostly math symbols and Greek letters.
(numeric entities) - An entity in the form "&#D;", where D is a decimal number in the range of 32-126 or 160 to 255 (inclusive). 16 bit Unicode numeric entities can also be validated with this built-in entity if enabled in the Validator Options. Hexadecimal entities in the form "&#xH;", where H is the hexadecimal value of the entity, can also be validated if enabled in the Validator Options.
(special entities) - Named miscellaneous entities.

The entities contained in the built-in named entity lists are displayed in the list boxes to the right of the Character Entities List Box. You can only view these entities.

Combo Boxes
