Emoji not working

See docsify-themeable’s emoji demo

• https://jhildenbiddle.github.io/docsify-themeable/#/markdown?id=emoji

It appears the CDN used for emoji images is having issues or is no longer used for this purpose by GitHub.

For example, this markdown:

:thumbsup:

Is rendered as follows by docsify:

<img class="emoji" src="https://assets-cdn.github.com/images/icons/emoji/thumbsup.png" alt="thumbsup">

Here’s how tne same emoji is rendered as part of a GitHub issue:

<g-emoji class="g-emoji" alias="+1" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f44d.png">👍</g-emoji>

Note the rendering method (rendering an actual emoji character) and the use of a different URL as a fallback. The official unicode emoji list may be helpful if/when docsify’s emoji output is updated.

When is this expected to be fixed?

According to caniemoji.com, unicode emoji are supported all the way back to Windows 7, macOS 10.7, Android 4.4, and iOS 5. Switching to unicode emoji would remove emoji <img> requests and render emoji native to each platform. Seems like a better route to go, so long as the unsupported OS+Browser combinations aren’t a concern. This article will likely be helpful if/when the switch to unicode happens.

@sio-funmatsu – Swapping the URL may be a workable short-term fix, but I wouldn’t recommend it as a permanent fix since this same thing can happen again if GitHub decides to host their emoji images in a new location. If we go this route, I’d recommend using GitHub’s emoji <=> image mapping available via https://api.github.com/emojis. If we wanted to stick with images long-term, it would be better to reference open source or (free) licensed emoji images available on a CDN such as EmojiOne. Docsify would qualify for a free license, allowing it to import the images directly into the docsify repo, which could then be referenced on jsDelivr for free. This would remove the dependency on GitHub’s emoji images and add support for additional emoji as well.
