TreeView.insert throws UnicodeDecodeError












0














I'm trying to populate TreeView with data from os.listdir(path).



All is ok until I read a directory name with a non-utf character. In my case 0xf6 which is not utf8.



As I'm running on Windows the charset from os.listdir() is Windows-1252 or ANSI.



How can I solve this problem to achieve correct display in TreeView?



Here some of my code:



def fill_tree(treeview, node):
if treeview.set(node, "type") != 'directory':
return

path = treeview.set(node, "fullpath")
# Delete the possibly 'dummy' node present.
treeview.delete(*treeview.get_children(node))

parent = treeview.parent(node)
for p in os.listdir(path):
ptype = None
p = os.path.join(path, p)

if os.path.isdir(p):
ptype = 'directory'

fname = os.path.split(p)[1].decode('cp1252').encode('utf8')

if ptype == 'directory':
oid = treeview.insert(node, 'end', text=fname, values=[p, ptype])
treeview.insert(oid, 0, text='dummy')

  • There are many matches for "treeview" on PyPi. Which library are you using specifically? And: what type are the offending dictionary keys, str or unicode?

  • O sorry, I did'nt read carefully. I meant "directory name". But I'm pretty sure os.listdir() returns str, not unicode. You can decode the directory name using name.decode('cp1252'), which gives you a Unicode string. Then check if TreeView.insert accepts this.

  • I tried name.decode('cp1252').encode('utf8') and it works fine. But I get into trouble when I continue looping through the directory tree - os.path.isdir(p) does not work as desired with utf encoding? Catch-22 situation?

  • Sounds like you need to keep to separate variables: the CP-1252 version for os.* and the UTF-8 version for the TreeView. Or you switch to Python 3, where everything should work with Unicode strings.

The UnicodeDecodeError is due to passing byte strings when the function is expecting Unicode strings. Python 2 attempts to implicitly decode byte strings to Unicode. Use Unicode strings explicitly instead. os.listdir(unicode_path) will return Unicode string, for example os.listdir(u'.').
