Hm. I still don’t understand the problem after having read the topic.
If I choose “movie” then I’m able to search and assign the tag via UI.
So it seems that emojis are stripped in searches and a pure emoji string therefore is not a valid search term?
My conjecture is that the translation of emojis into their Markdown equivalent is also a contributing factor.
Are there any downsides to use emojis in tag names, which would favor emoji-free tag names decorated with Tag Icons in the UI?
