Unicode support in text/heading elements

[jneubrand]

Unicode characters such as 🎉 (should be encoded as 🎉) throw an InvalidCharacterError instead of being encoded as an HTML entity.

So it seems base64 encoding is not actually necessary. I'm testing with some different phones but we might be able to solve this by just not base64 encoding the data URI

#56 resolves this but only for characters like ♥ or 這. Emoji should still be encoded as HTML entities because they show up as blank spaces in editors. Though I suppose that's up to developers.

Fair enough. Closing this

Will be closed when #56 gets merged.
