) [private]

testFileIndexing(self, file, handler, output_encoding) => dict
the dict keys are :
  - content_type: MIME type
  - content_length: length
  - filename: filename (!)
  - raw_content: file.read()
  - index: indexable value
  - preview: html preview
  - encoding: same as output_encoding
handler id and output encoding must be provided.
