==About==
==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 "&amp;" (ampersand) and end with ";" (semicolon). Many entities have mnemonic names (such as "&amp;amp;", which displays an ampersand); any possible character can be displayed as an entity by using the format "&amp;#<u>number</u>;" where <u>number</u> is the output character's [[ASCII]] value in decimal.

* 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: '''&#70;&#82;&#69;&#76;&#71;&#75;&#76;&#79;&#84;&#90;''')

* 0-8 are not translated
* '''2017-11-11''' MediaWiki 1.28.0 apparently no longer supports the "&amp;#d;" style of entity; you now have to use named entities.
* 9 is probably TAB
* '''2020-05-23''' This seems to have been fixed?
* 10 is probably [[linefeed|LF]]
* 13 is probably [[carriage return|CR]]
* 14-31 are not translated
* 32 is a standard space

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 "&amp;", 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.

Questions

  • Do search engines 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 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?
