AW: Python2.6 + win32com crashes with unicode bug
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-aeb6-45664be858b6displaylang=en and check the parameters.
