HTML entity

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.

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).
