Feature or enhancement

The _PyUnicode_Name_CAPI provides functions to get the name for a given Unicode character code and vice versa. It is lazily initialized and stored in the per-interpreter _Py_unicode_state:

The initialization of the ucnhash_capi isn't thread-safe without the GIL. (There can be a data race on reading and writing ucnhash_capi).

Mostly for my own reference, here are the similar modifications in the nogil-3.12 fork: colesbury/nogil-3.12@5d006db9fa
