> I was hoping they had standardized how emoji look across platforms. You can't really do this. Or, rather, it's already been done, but people choose not to do this. Emoji are just unicode characters. How they're displayed depends on the font used. Everyone could choose to use the same emoji font across platforms or apps, but they don't. The one announced here is open source, for instance, but there's no way Apple is…
> You can't really do this. "We've agreed with Apple to use their emoji glyphs on Android by default regardless of font, unless overriden by the user. We understand users might prefer the current designs, and we are proud of the work our team has done, but we believe that consistent communication is more important, and individual users can always enable the override to get the old look back." > Everyone could choose…
> Yeah, that's the problem. We can't rely on every user going out of the way to drive adoption, it has to be done centrally.
Well by "everyone" I meant platform companies, app makers, and website designers. There's literally no way you'll get them to agree on a font choice.
> "We've agreed with Apple to use their emoji glyphs on Android by default regardless of font, unless overriden by the user".
First you'd have to get Apple to license their emoji font, presumably open source and freely available if you truly want it to be standardized across platforms. Have they ever open sourced a font? Or get Apple to agree to use someone else's font as the system default. Have they ever done that?
Second, if you forbid app developers from choosing an emoji font, the Facebooks of the world are just going to work around you by stripping out the emoji and manually inserting theirs in. Somewhat ironically, by ignoring the platform emoji font, which can lead to some jarring text rendering if you're used to the system font, apps like Facebook are fulfilling your dream of standardized unicode across platforms...but of course, only for users of their apps.
Third, I think you really underestimate the fundamental disagreements here. The Unicode Technical Committee has a working group to try to improve unicode interoperability, and victories are on the level of getting vendors to agree if the standard for the Lotus emoji should mention that it shouldn't include a lillypad (they decided no[1]). They're working on this, but it's never going to be what you want.
In any case, I understand what you're saying and I wasn't dismissing the fact that the precise emoji design can influence why you used that emoji at all, which gets lost in the translation to another emoji font.
