Encoding with pandas.read_csv when file name has accents

Question

I'm trying to load a CSV with pandas, but am running into a problem if the file name has accents. It's clearly an encoding problem, but although read_csv lets you set encoding for text within the file, I can't figure out how to encode the file name properly.

input_file = r'C:\...\Datasets\%s\Provinces\Points\%s.csv' % (country, province)
self.locs = pandas.read_csv(input_file,sep=',',skipinitialspace=True)

The CSV file is Anzoátegui.csv. When I'm getting errors,

input_file = 'C:\\...\Datasets\Venezuela\Provinces\Points\Anzoátegui.csv

Error code:

OSError: File b'C:\\PF2\\QGIS Valmiera\\Datasets\\Venezuela\\Provinces\\Points\\Anzo\xc3\xa1tegui.csv' does not exist

So maybe it's converting my string to bytes? I tried using io.StringIO(input_file) as well, which puts the correct file name as a column header on an empty DataFrame :

Empty DataFrame
Columns: [C:\PF2\QGIS Valmiera\Datasets\Venezuela\Provinces\Points\Anzoátegui.csv]
Index: []

Any ideas on how to get this file to load? Unfortunately I can't just strip out accents, as I have to interface with software that requires the proper name, and I have a ton of files to format (not just the one). Thanks!

Edit: Full error

Ok folks, I got a little lost in dependency hell, but it turns out that this issue was fixed in pandas 0.14.0. Install the updated version to get files named with accents to import correctly.

Comments at github .

Thanks for the input!
