""" Read a DXF document from a binary-stream similar to :func:`ezdxf.read`,
but this function will detect the text encoding automatically and repair
as much flaws as possible, runs the required audit process afterwards
and returns the DXF document and the :class:`Auditor`.
Args:
stream: data stream to load in binary read mode
errors: specify decoding error handler
- "surrogateescape" to preserve possible binary data (default)
- "ignore" to use the replacement char U+FFFD "\ufffd" for invalid data
- "strict" to raise an :class:`UnicodeDecodeError` exception for invalid data
Raises:
DXFStructureError: for invalid or corrupted DXF structures
UnicodeDecodeError: if `errors` is "strict" and a decoding error occurs
