Hello Gerrit,
there is no problem in the file, but in the description of the Visio API. The
place where the error occurs is during the definition
of the parameters of the corresponding Python methods. The information for the
names comes from the typelibrary of visio. Probably there is a
non english name inside the typelibrary (MS used native names in early Office
products) which then could not decoded to a correct Python name.
In my Version of Vsio OpenEx has two parameters called FileName and Flags. You
have to look in your typelibrary, e.g. with OleView
http://www.microsoft.com/downloads/details.aspx?familyid=5233b70d-d9b2-4cb5-aeb6-45664be858b6&displaylang=en
and check the parameters.
Regards
Stefan

the string "D:/temp/test.vsd" itself does not contain any
charactervalue>128:
>>> for c in "D:/temp/test.vsd":
print ord(c), " ",
68 58 47 116 101 109 112 47 116 101 115 116 46
118 115 100
(on my current Python 2.5 configuration)
The presumably binary file itself may contain any value, but I don't
expect Python or win32com to do anything with the file content...
There are explanations on internet that Windows uses internally 2
(incompatible) API's that cause poblems with Unicode based filenames. I
do something like that to be the problem in Python 2.6
kind regards, Gerrit
