Including web fonts and available system fonts. naming for such property could be availableFonts and the array value return could be read only. Such interface would be useful for providing font pickers in graphical applications etc. Currently the only existing walk around to this issue is using flash which isn't very help full when not all devices support it.

Currently there are also workarounds that instantiate a font for a specific string, checks the TextMetrics measureText, and then decides whether the font exists (http://www.lalit.org/lab/javascript-css-font-detect/) assigned to HTML.Next for consideration. 73223 3 robin 2012-09-05 12:36:55 +0000 Please keep in mind that there are substantial fingerprinting issues with listing system fonts (see http://panopticlick.eff.org/). While I agree that useful ways of manipulating font information would often be great, we have to be careful that this does not make users uniquely identifiable without cookies. 81660 4 robin 2013-01-21 15:57:57 +0000 Mass move to "HTML WG" 81775 5 robin 2013-01-21 16:00:41 +0000 Mass move to "HTML WG" 83596 6 eoconnor 2013-02-22 21:12:56 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
