Add PyUnicode_AsUTF8() function to the limited C API. multiprocessing posixshmem now uses PyUnicode_AsUTF8() instead of PyUnicode_AsUTF8AndSize(): the extension is built with the limited C API. The function now raises an exception if the filename contains an embedded null character instead of truncating silently the filename.

I just modified the function in PR #111091 to raise an exception if the string contains embedded null characters. |

Why not simply use the str converter?

Ah, I see why. path is passed to PyErr_SetFromErrnoWithFilenameObject().
