> Should we add an explicit check on variable char_size before using it in division?

Search for "There are 4 forms of Unicode strings" in Include/cpython/unicodeobject.h. char_size cannot be 0 in resize_compact(): it's checked by 2 assertions:

    assert(PyUnicode_IS_READY(unicode));
    assert(PyUnicode_IS_COMPACT(unicode));

The function cannot be called on a string which is not compact.

There is no bug, I close the issue.

Hopefully, Inada-san will remove state.compact field in Python 3.12 with his PEP 623!
