Python compatibility with R in pen with strings

I am making an error while reading a pen object in R that has been removed from a python session.

In python:

In [248]: import pandas as pd

In [249]: pd.DataFrame({'col': ['a','b','c']}).to_feather('strings_df.feather')

In R:

> library(feather)
> df = read_feather('strings_df.feather')
Error in coldataFeather(x, i) : 
  RAW() can only be applied to a 'raw', not a 'list'

Is this because strings are stored as objects in pandas.Series? Any thoughts on what's going on here?
