Star emoji ⭐ not rendered correctly

Describe the bug

The star emoji ⭐ (“White Medium Star”, U+2B50). Does not get rendered correctly (see screenshot below). It is missing the yellow color and is a lot smaller than other emojis.

All other emoji that I tried work as expected.

Steps to reproduce the bug

<Button>&#x2B50;</Button>

You can also see this bug when you copy a star emoji (or use the emoji picker) into the search field in the “WinUI 3 Controls Gallery”. However, this issue is not specific to the sample app and reproduces for me in all places that I tried.

Expected behavior

The yellow Microsoft style star emoji should be rendered. https://emojipedia.org/star/

Additional context

Please let me know if any more information on this issue would be helpful to solve this issue.

As the star is quite old (Unicode 5.1) I tried some other emoji from that generation and even older ones, but I was not able to find any other emoji that have the same issue.

Yes, weird When no font is specified, it uses “Segoe UI” and both should be colored, according to : https://www.fileformat.info/info/unicode/char/2b50/index.htm https://www.fileformat.info/info/unicode/char/263a/index.htm

This is by-design from Unicode. In general the correct solution isn’t to force the font, you need to use the variation selector codepoint to force the colored emoji to show.

(So you put the star emoji and the next character (before the space or anything) should be U+FE0F)
