About AmpWhat

Amp What is a quick, interactive reference of 33,212 HTML character entities and common Unicode characters, 8859-1 characters, quotation marks, punctuation marks, accented characters, symbols, mathematical symbols, and Greek letters, icons, and markup-significant & internationalization characters.


  1. Unicode.org, “Latest Unicode.org international character reference”
  2. Unicode.org, “CLDR Data”
  3. Unicode.org, “Emoji Data” and “Emoji Sequences”
  4. W3, “HTML entities”
  5. W3, “Using character escapes in markup and CSS”
  6. I originally built Amp-what using Remy Sharp's excellent supplement and lots of my own annotations. I imported documents such as hacker jargon, and added 100s of my own annotations as a result of watching for zero-result searches by users. At this point, much of this data is included in Unicode reference documents, so now AmpWhat mainly presents the Unicode reference materials in a way I think is most useful.
  7. Thanks to Mathias Bynens for correcting me several times, but more importantly, for contributing immensely to the subtle craft of drawing text. His name pops up whenever I have a question about something tricky. AmpWhat also uses jsesc.
  8. Steve Deach, an early mentor, got me interested in text layout, typography, and I dare say, SGML-- before it was hip.
