Title cards do not support emoji

[robby1066]

Describe the bug

If a clip title contains an emoji character (examples: 👋🤦‍♂️🎉), it is not displayed on the generated title card.

Steps To Reproduce

1. Go to compose a message
2. Create a 'custom subject' clip
3. Include an emoji in the clip title
4. Create the message
5. Observe the generated title card

Expected behavior

It's expected they would show on the title cards if they are used. Emojis are commonly used, and they are an easy way to add a graphic element to title cards.

Screenshots

Testing suggests that the encoding of the HTML page that the title image is rendered from is an issue. Not sure if that's the only issue, but running a few more tests to figure it out.

Making some progress on this one, emojis on title cards have gone from looking completely insane to simply looking broken, which suggests that this is both an encoding issue and a missing font on the server.

Looks like after installing an emoji font on the server, emojis are rendering correctly. The emoji font may look different than the user's system font. That's unavoidable, although there are some options for which emoji font is used by the system.

The server the font is now using is Noto Color Emoji: https://www.google.com/get/noto/help/emoji/

Here is the same image from the original issue ☝️ rendered with working emojis.

I'll do some final testing on it, and make sure future deploys don't cause problems before closing.
