One more 'problematic' symbol - "清". Files containing these characters
_can_ be uploaded via browser, but not using .NET GData client

The exact error looks like that:
System.ArgumentException: Specified value has invalid Control
characters. Parameter name: value
at System.Net.WebHeaderCollection.CheckBadChars(String name,
Boolean isHeaderValue)
at System.Net.WebHeaderCollection.Add(String header)

target, String slug, String contentType, Int64 contentLength)
