Yes, but only general-purpose fonts, not math-specific. Also, if text is rendered with a different font face (because system lacks requested font) it's remains readable. > And Web fonts exist to work around the lack of system fonts. Yes, but what if web developer is not careful enough and assumes that if mathml is present, then math font is available? > As a Web Platform developer, I believe browser sniffing is bad practice, so I > hope people > use other techniques to provide alternate content. What do you mean under "browser sniffing"? UA string sniffing is a shame, certainly. But feature testing (e.g. by checking size of <mspace>) is a valid appoach. -- Regards, Konstantin _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
