CI: Exception ignored in: 'pandas._libs.tslibs.util.get_c_string_buf_and_size'
Seen in the logs lately:

```
Exception ignored in: 'pandas._libs.tslibs.util.get_c_string_buf_and_size'
UnicodeEncodeError: 'utf-8' codec can't encode character '\ud83d' in position 0: surrogates not allowed
```

Possibly related to #32701?
