Defaults to "Bytes object". This function should never error out and so can take a best effort approach. It is okay to be lossy if needed since the return value is just for display. We assume the data is in the locale preferred encoding. If it won't decode properly, we warn the user but decode as best we can. We also ensure that the output can be safely written to standard output without encoding errors. �asciizutf-8z&%s does not appear to be encoded as %sz Bytes object�errors� __stderr__N�encodingr2 )� isinstancer �locale�getpreferredencoding�codecs�lookup�name�decode�UnicodeDecodeError�logger�warningr1 �getattr�sys�encode)�data�descr; � decoded_data�output_encoding�output_encodedr r r �str_to_displayb s* rN c C s t | d d �S)z<Return a string, safe for output, of subprocess output. rJ zSubprocess output)rN )rI r r r r � s c C s� t t d � rM t j | t j t j B� } t j | � j } t j | � n< t j j | � st t j | � j } n t d j | � � � | S)a) Return path's uid.
