Code Review
This pull request updates Windows clipboard handling to correctly process and replace embedded null characters with the replacement character \uFFFD, and transitions string parameters to std::string_view to support explicit lengths. Feedback recommends removing top-level const qualifiers from std::string_view parameters passed by value in function declarations, definitions, and mock methods, as they are redundant and add visual noise.

This looks like a solid change, thanks!
I just have a documenting request so that the quirk is obvious to future readers of this code.

Closes #162226.
Sadly win32 doesn't allow
\0characters inside theCF_UNICODETEXTclipboard. To prevent it, I replaced the null terminator with the\uFFFD(replacement character: https://www.compart.com/en/unicode/U+FFFD).I replaced the string type to a string view to also store the size on the way so it doesn't break on the way if there are null terminators.
Currently a draft since I don't have tests yet.Pre-launch Checklist
