#### Question about pandas

```python
df = pd.DataFrame([ ['a\rb'] ], columns=['A'])
df.to_csv('df.csv', index=False, sep=';', encoding='utf-8')
df_imported = pd.read_csv('df.csv', sep=';', encoding='utf-8')
(len(df), len(df_imported)) # => (1, 2)
```

On Linux, symbol `\r` is not escaped by `pd.to_csv`. But seems like `pd.read_csv` expects something else.

Is it bug or feature? How to avoid this?
