## Summary
Ensures that we use the raw identifier as provided in the source code,
rather than the normalized Unicode identifier.
This _does_ mean that we treat these as two separate identifiers, and
_don't_ merge them, even though Python will treat them as the same
symbol:
```python
import numpy as ℂℇℊℋℌℍℎℐℑℒℓℕℤΩℨKÅℬℭℯℰℱℹℴ
import numpy as CƐgHHHhIILlNZΩZKÅBCeEFio
```
I think that's fine, this is super rare anyway and would likely be
confusing for users.
Closes https://github.com/astral-sh/ruff/issues/10528.
