Markdown emojis not rendering on webpage

[mertall]

Hello, I am trying to utilize markdown emojis. When I insert an emoji as ':emoji_title:' it renders in markdown preview but does not display on my site, rather only comes out as the character values on the webpage.

Same question here

Not an expert but seems related to UTF-8. And I just found directly copy paste emoji works, e.g. from here https://emojipedia.org/!

It looks like this is referring to extended emoji like the ones in this list - those don't appear to be part of the basic Markdown installation so I'll have to see how to enable them.
