About
An HTML entity is a combination of characters which will be displayed within an HTML browser as a single character. All HTML entities begin with "&" (ampersand) and end with ";" (semicolon). Many entities have mnemonic names (such as "&", which displays an ampersand); any possible character can be displayed as an entity by using the format "&#number;" where number is the output character's ASCII value in decimal.

Reference
- Wikipedia
- HTML 4.0 entities
- Named character references, in alphabetical order, including newer ones not supported by most browsers
- HTML Entity List: "Complete list of HTML entities with their numbers and names. Also included is a full list of ASCII characters that can be represented in HTML (i.e. printable characters)."
Questions
- Does Google resolve html entities when indexing web pages? That is, if I spelled a word (e.g. "schmerglefrotz") entirely using html entities, would someone be able to find that page using google by typing "schmerglefrotz" (after the site had been spidered, of course)? (As a test, I will spell a completely different word using HTML entities, and try Googling it later: FRELGKLOTZ)
- 2007-07-15 answer: Yes, it does find it (though it took several months at least before this page got indexed).
- 2016-11-28 answer: Searching for the word in question no longer produces any results. Neither does searching for "schmerglefrotz".
Note
- 2017-11-11 MediaWiki 1.28.0 apparently no longer supports the "&#d;" style of entity; you now have to use named entities.
- 2020-05-23 This seems to have been fixed?
Entities by Number
- 0-8 are not translated
- 9 is probably TAB
- 10 is probably LF
- 13 is probably CR
- 14-31 are not translated
