How to work around a unicode problem?

[tinnews]

I have a small python program that uses the pyexiv2 package to view
exif data in image files.

I've hit a problem because I have a filename with accented characters
in its path and the pyexiv2 code traps as follows:-

Traceback (most recent call last):
File "/home/chris/bin/eview.py", line 87, in <module>
image = pyexiv2.ImageMetadata(filepath)
File "/usr/lib/python2.7/dist-packages/pyexiv2/metadata.py", line 65, in __init__
self.filename = filename.encode(sys.getfilesystemencoding())
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 38: ordinal not in range(128)

Without digging deep into pyexiv2 is there any way I can work around
this error? The accented characters aren't in the filename itself,
they're in the directory path. I.e. it's:-

./1977/04 April/#09 - Monaco, inc. Musée de Poupée/p77_08_011.jpg

I could of course remove the accents but I'd much prefer not to do so.

they're in the directory path.

After glancing at the docs, (untested):

with open(filepath) as f:
image = pyexiv2.ImageMetadata.from_buffer(f.read())

Cheers,

Try passing a unicode filename. A quickfix:

filepath = filepath.decode(sys.getfilesystemencoding())
image = pyexiv2.ImageMetadata(filepath)

If you are using os.listdir() or glob.glob() to produce the filepath -- they
will return unicode filenames if you invoke them with a unicode argument.

Excellent, worked perfectly (after I spotted I had another variable f).

Thank you.

.... and this solution works too, thank you.
