Just started… and already stuck :-/ Seems like the parser doesn't like UTF-8:
Try 1
"FastKML reads KML snippets from strings rather than files. Reading files using Pythons standard document parser makes assumptions about encoding and it the UTF / Unicode encoding string is forwarded to lxml it does not want to parse it and wants to perform its own interpretation or obtain the data as raw bytes. It would be good to extend fastKML to include a from_file method in the parser to circumvent this and pass the file directly to lxml for encoding interpretation etc. […] The error is indicative of encoding conflicts and direct parsing from files will be really useful for my use-cases."
