Pandas read_sas error: 'ascii' codec can't decode byte 0xd8 in position 0: ordinal not in range(128)
Hello everybody,

I am using **Pandas 0.18** to open a `sas7bdat` dataset 

I simply use:

```
df=pd.read_sas('P:/myfile.sas7bdat')
```

and I get the following error

```
    buf[0:text_block_size].rstrip(b"\x00 ").decode())

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd8 in position 0: ordinal not in range(128)
```

If I use

```
import sys
reload(sys)
sys.setdefaultencoding("utf-8")
```

I get

```
UnicodeDecodeError: 'utf8' codec can't decode byte 0xd8 in position 0: invalid continuation byte
```

Other `sas7bdat` files in my folder are handled just fine by Pandas. 

When I open the file in SAS I see that the column names are very long and span several lines, but otherwise the files look just fine.

There are not so many possible options in `read_sas`... what should I do? Is this a bug in `read_sas`? 

Many thanks!
