Can't open WebDAV folders or files with non ASCII characters

[diggy128]

I tried moving to webdav_fast to also use your other cardav modules but have come up to following bug:
If the folder that is to be browsed contains non ascii characters I can't enter into.
The console just outputs:
'ascii' codec can't decode byte 0xce in position 0: ordinal not in range(128) 2016-05-07 20:49:04,852 31171 INFO ******* werkzeug: 127.0.0.1 - - [07/May/2016 20:49:04] "PROPFIND /webdav/*********/%CE%92%CE%B9%CE%B2%CE%BB%CE%B9%CE%BF%CE%B8%CE%AE%CE%BA%CE%B7/ HTTP/1.1" 404 -

A similar message appears when trying to access (aka read) files that contain non ascii characters and a message shows that the file does not exist (although it exists and is visible from odoo backend).

I'm guessing this has to do with how folder/file names are handled and most likely can be easily fixed.

I'm using openERP v7.
Any chance of providing a patch?

PS. The old document_webdav from odoo works fine with all folders and files.
