scriptableapplication crashes with non-UTF-8 locale

examples/scriptableapplication crashes on RHEL 7.9 with FIPS enabled, but does not crash on an identical RHEL 7.9 machine without FIPS enabled.  The crash occurs here:

(gdb) bt
#0  PyObject_SetAttrString (v=0x0, name=0x7ffff7ec1120 "Enum", w=0x0)
    at Objects/object.c:818
#1  0x00007ffff7e992cf in _init_enum ()
    at /home/jp/Qt/pyside-setup-Qt-6.4.2-linux-g++-64-python39-pydebug-debug/sources
/shiboken6/libshiboken/sbkenum.cpp:381

The problem is the import of "shiboken6.Shiboken" returns a null ptr, leading to the crash.

This crash does not occur when using Qt 6.2.4.

The crash appears identical to the crash in Bug PYSIDE-2218, making it possibly related.
