Issue #13441: Disable temporary the check on the maximum character until
the Solaris issue is solved. But add assertion on the maximum character in various encoders: UTF-7, UTF-8, wide character (wchar_t*, Py_UNICODE*), unicode-escape, raw-unicode-escape. Fix also unicode_encode_ucs1() for backslashreplace error handler: Python is now always "wide".
