In that case, I think we should hold off on (4) until it's tested for a decent variety of different applications, or at the least consider leaving it off by default (unticked checkbox) with a note of some form that warns users of the possible legacy incompatibility with MBCS. I'll admit though that I have no experience working with any application that implicitly assumes MBCS is the default encoding format, is this a common occurrence in some older applications? I could imagine this being the case in legacy applications that need international encoding, but I have zero idea of how common it is in reality. As a side note, Microsoft recommends not using MBCS for encoding in newer applications in their Visual C++ docs: "MBCS is a legacy technology and is not recommended for new development." ( https://docs.microsoft.com/en-us/cpp/text/support-for-multibyte-character-sets-mbcss?view=vs-2019 ). This might also be useful for getting a general idea of MBCS expectations when it comes to Windows development, although some of it is specific to C++: https://docs.microsoft.com/en-us/cpp/text/general-mbcs-programming-advice?view=vs-2019 .
