Swap out marked.js for markdown-it

[miketaylr]

See https://github.com/markdown-it/markdown-it. Actively maintained and has a plugin architecture. 👍

TODO

• rip out marked, add in markdown-it
• configure langPrefix so syntax highlighting still works (by default it's language-, which is what we want).
• figure out how to rehide the html comment hax
• emoji plugin https://www.npmjs.com/package/markdown-it-emoji
• sanitizer plugin https://www.npmjs.com/package/markdown-it-sanitizer

investigate https://www.npmjs.com/package/markdown-it-hashtag as a hackable replacement for issue linking, or possibly https://www.npmjs.com/package/markdown-it-for-inline.

Sweet, this markdown parser is already so much nicer.

So the way this thing deals with emoji is to map to the real unicode emoji codepoint. So that leaves out some older browsers. See #260 (comment) for the plan on how I think we should proceed (tl;dr, if someone complains about lack of support in older browsers, we add in support for serving images).

Instant love. ;) I think it's fine to avoid image overload.
Talking about feature detections vs user agent sniffing. How do you detect in a code if you can send a unicode point or an image.

Hmm i guess by testing if the value returns the generic character

String.fromCharCode(0x1F6C8) 

will return a generic icon for missing character (maybe different depending on the browsers).
hmmm…

I wonder if @mathiasbynens hasn't solved this problem before... (re: feature detection)

[mathiasbynens]

Well there’s https://github.com/Modernizr/Modernizr/blob/master/feature-detects/emoji.js which detects if an emoji renders as expected or not. You could do something similar for other characters.

Ah, that’s basically what http://stimulus.hk/demos/testFont.html (which @karlcow already mentioned) does. So there!

thx!
