…he Windows console (pythonGH-124059) Since MultiByteToWideChar()/WideCharToMultiByte() is not reversible if the data contains invalid UTF-8 sequences, use binary search to calculate the number of written bytes from the number of written characters. Also fix writing incomplete UTF-8 sequences. Also fix handling of memory allocation failures. (cherry picked from commit 3cf83d9) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
