Feature or enhancement

Proposal:

If function_io__WindowsConsoleIO_write_impl does not produce as expected output from WriteConsoleW, it is the process of recalculating the existing len.

At this point, function WideCharToMultiByte finds the byte length of utf-8 and function MultiByteToWideChar finds the letter length of utf-16. And is this comparison valid for comparing the results of these two?

Has this already been discussed elsewhere?

I have already discussed this feature proposal on Discourse
