It gets weirder. Hovering the large `Ｓ` here shows the text for [Fullwidth Latin Capital Letter T](https://unicode-table.com/en/FF34/). Clicking it and pasting here, we get: `Ｔ`. Pasting that `Ｔ` into egui will make it sometimes show up as `Ｓ`, and sometimes as `ｔ` (lowercase!) depending on where in `egui` you paste it into.

Start by reproducing the fullwidth-character behavior described in the issue, including hovering, clicking, and pasting the characters into different egui locations. The payload names no source file, entry point, or test, so trace the relevant text input and rendering paths. Done means pasted fullwidth characters display consistently with their original character and case.
