1) Create any kind of text area by selecting Toolbar -> Add -> Text -> (any option).
2) Open up the Special Characters panel and insert several characters under Mathematical Alphanumeric Symbols section.
3) Copy the special characters and paste into the same box. Musescore shows Hangul characters instead (For instance, 𝕗 U+1D557 turns into 핗 U+D557 predictably).
4) Backspace one of the special characters then undo (ctrl+z). The character transforms into anything between �, 🀀, and the default tofu block.

However, it is true that copy/paste does not do a great job with special characters in general. I've never seen this specific result, though, so we'd need more precise steps - including a sample score - to investigate further. That way we know exactly which fonts and characters are involved.

I appreciate the quick response.

Steps to reproduce

1) Open broken_unicode_demo.mscz.
2) Double click the title block to edit.
3) Open the Special Characters panel using the button on the bottom left.
4) Go to Unicode Symbols -> Mathematical Alphanumeric Symbols.
5) Insert the first three characters on the list: 𝐀𝐁𝐂.
6) Copy the three characters in the text box and paste into the same box. The characters now transform into 퐀퐁퐂.
7) Delete the 𝐂, then hit ctrl+z. The character reappears as �. Exit the text box by clicking elsewhere. The � and the 퐀 characters combine into the ubiquitous question tofu block.
