Inline approvals chokes on special unicode characters

```python
def test_unicode_and_special_characters() -> None:
    """
    e\u0301
    """
    text = "e\u0301" # 'e' + COMBINING ACUTE (2 code points)
    verify(text, options=Options().inline())
```

Result:

```
E       UnicodeEncodeError: 'charmap' codec can't encode character '\u0301' in position 1: character maps to <undefined>
```
