AI-generated summary
Broken Emoji Issue: Some emojis, specifically those from the category, were not displaying correctly. Lutz reported the issue, and David_Collantes confirmed it on meta. codinghorror identified it as a bug and assigned it to tgxworld for investigation.
The issue was caused by the addition of the win10 emoji set, which introduced a bug where emojis not available in the win10 set would break when running the emoji update script. tgxworld proposed a solution to support all emojis in each set, but codinghorror suggested forcing the Windows 10 Emoji set to use the same names as other sets.
tgxworld ultimately implemented a fix to only support the intersection between emoji sets, resolving the issue of broken emojis. The fix is available in the commit ba21ef34e5b386cc1c87fc38a97fb610bd3dcd9a.

Topic should be changed too. Some Emoji will not show, or show broken. Confirmed on meta.

Hmm this is a bug. Can you look into it @tgxworld?

Ok I took a deep dive here to figure out the root cause of the problem:
Previously, Discourse would only pull down emojis that are available across all the emojis sets that we support. However, the addition of win10 emoji set introduced a bug where emojis that are not yet available in the win10 emoji set would cause the emoji to break when we run the emoji update script. After digging through the code, it was clear to me that we need a better pattern here so that we can support all emojis that are in each emoji set.

The correct fix is to force the Windows 10 Emoji set to have the same names as all the other emoji sets. I hand created some missing emoji for the set, what happened to them?
Looks like we want to only support the intersection between the emoji sets so I’ve pushed the fix for the broken emojis for now.
