Changing filenames from Greeklish => Greek (subprocess complain)

[Νικόλαος Κούρας]

Okey after reading also Steven post, i was relived form the previous suck position i was, so with an alternation of a few variable names here is the code now:


#========================================================
# Collect directory and its filenames as bytes
path = b'/home/nikos/public_html/data/apps/'
files = os.listdir( path )

for filename in files:
	# Compute 'path/to/filename'
	filepath_bytes = path + filename
	for encoding in ('utf-8', 'iso-8859-7', 'latin-1'):
		try: 
			filepath = filepath_bytes.decode( encoding )
		except UnicodeDecodeError:
			continue
        
		# Rename to something valid in UTF-8 
		if encoding != 'utf-8': 
			os.rename( filepath_bytes, filepath.encode('utf-8') )

		assert os.path.exists( filepath )
		break 
	else: 
		# This only runs if we never reached the break
		raise ValueError( 'unable to clean filename %r' % filepath_bytes ) 

=================================

I dont know why it is still failing when it tried to decode stuff since it tries 3 ways of decoding. Here is the exact error.
