latin-1 codec cant encode characters in position 42-48:ordinal not in range256

What to do:

Check cause: Found file name has Chinese name, so cause error, encoding is LATIN-1 encoding, so we need to decode into Unicode encoded into latin-1

Look at the code first:

This code involves a Python transcoding problem, be sure to note

                Filepathname = Self.get_argument ("filepathname"# Gets the file name filename                = STR (filepathname.split ("/") [-1]). Strip () # Gets the                file name = Filename.encode ( " Utf-8 "). Decode ("latin1"#  This sentence is very important, to parse into latin-1 only OK, so that will not error

Decode ("latin1")#This sentence is critical, to parse into latin-1 is OK, so that will not errorNewFileName = str (int (time.time ())) +"."+ Filename.split (".")
