Should this work?

```
>>> mapnik.Expression("[foo]='Tom\'s'")
Traceback (most recent call last):
File "", line 1, in
RuntimeError: Failed to parse expression: "[foo]='Tom's'"
>>> mapnik.Expression("[foo]='Tom/'s'")
Traceback (most recent call last):
File "", line 1, in
RuntimeError: Failed to parse expression: "[foo]='Tom/'s'"
```
