** '''2007-07-15 answer''': Yes, it does find it (though it took several months at least before this page got indexed).
 
** '''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.

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.

see also: wikipedia:Percent-encoding

Reference

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.

Entities by Number

  • 0-8 are not translated
  • 9 is probably TAB
  • 10 is probably LF
  • 13 is probably CR
