The symbol _Py_DecodeUTF8_surrogateescape is not exported from Python.framework on macOS in Python 3.10.  The symbol was exported in earlier versions of 3.x.

I'm not sure if this was intentional, so far I haven't been able to find when this was changed.

This change breaks py2app which uses _Py_DecodeUTF8_surrogateescape to convert the C argv array to an array of 'wchar_t*' for use with Python's C API.

I've switched py2app to Py_DecodeLocale, which is a public API introduced in 3.5 to accomplish the same task. 

I'm leaving the issue open in case hiding the symbol is unintentional.
