Hi All: We need a path forward on the deployment of Icon fonts in FxOS. The Gaia team understandably wants to squeeze every bit of performance on their apps in v1.4: https://bugzilla.mozilla.org/show_bug.cgi?id=951593
We are concerned about leaking these fonts into Open Web content, so we want to restrict it to certified Gaia apps: https://bugzilla.mozilla.org/show_bug.cgi?id=1008458 The approach we take to restrict icon fonts to certified Gaia apps is under some debate, and we've got 4 possibilities: 1. Let people use the icon fonts anywhere. (ie. like "MS WingDings" can be used for this purpose) 2. The patch in bug 1008458 introduces "private" fonts that use the Unicode Private Use Area (PUA) for icon glyphs. 3. Use PUA characters as per bug 1008458 but disable use of PUA characters in local fonts on all platforms except for FirefoxOS certified apps. 4. Use the OpenType discretionary ligatures ("dlig") feature to hide the glyphs ( see https://bugzilla.mozilla.org/show_bug.cgi?id=1008458#c22 ) I'm afraid of the amount of code in the patch for bug 1008458 for the 1.4 release, so I'm inclined to let the Gaia team use the icon font as-is (option 1) with the promise that they won't use it in uncertified non-system apps. I also propose that we make any required code changes in v2.0 so that non-certified apps can't get unrestricted use of the font. All the options proposed (#2,3, or 4,) have drawbacks, the common one being that they may be overly restrictive. I'd like some feedback here, first on my proposal that we go with Option 1 for 1.4. Second, I'd like us to solve the font leakage problem for 2.0 with one of the 3 other proposals, if still needed--I'd like to see how far we get to improve SVG performance (bug 999931) to make all this a moot point. I really am not a fan of icon fonts (see https://twitter.com/73inches/status/468368206282113024/photo/1 ) Thanks, --Jet _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
