Apologies if this is a duplicate (I couldn't find anything obviously similar) but some emojis (e.g. keycap symbols (0-9)) are not rendered correctly using Ubuntu via Windows Terminal and was just wondering if I should expect this to work

@j4james commented on GitHub (Apr 5, 2021):

The reason the one works and the other doesn't is because keycap 10 has its own unique codepoint, while keycap 5 is actually multiple codepoints joined together (which isn't yet supported). I believe this is covered by issue #1472.

You know what, I'm guessing this is some combo of #1472, #8000 and #190. Emoji work alright if they're being output by a client app, but they really, really don't work when they're being input (like, and a powershell prompt)

/dup #190

Can you post a screenshot of the issue you're seeing? I'm maintaining our text renderer so I may be able to help (or fix it).

@lhecker commented on GitHub (Sep 4, 2025):

Those are keycap emojis which are a truly unique case among all emojis and are not well supported by Windows at all. Browsers are an exception since they (like us) implement their own text rendering. To support keycap emojis we need to add custom detection logic during MapCharacters (font fallback). That shouldn't be too difficult.

Is there anything else wrong?

I think the remaining work well.

I see. We have only to detect the pattern in the above image showing their code points.

🔟 is an independent code point.

Anyway I don't think there are any reasons to keep the status of this issue "resolved".
