The folloing string:
%2c%e3%80%90%e5%bd%a2%e3%80%91%e6%97%a0%e7%a2%8d%e7%9a%84%e3%80%82
Pass to the following function
def HexStringToString(hexString):
# convert hex string to utf8 string
# example: "%2c%e3%80" -> "\x2C\xE3\x80"
bytes = []
hexStr = ''.join( hexString.split("%") )
for i in range(0, len(hexStr), 2):
bytes.append( chr( int (hexStr[i:i+2], 16 ) ) )
# decode as utf8
string = ''.join( bytes ).decode("utf-8")
return string
Will become

Pass again to the following function
def StringToHexString(string):
# convert string to hex string
string = string.encode('utf8')
return ''.join( [ "%02X " % ord( x ) for x in string ] ).strip().replace(' ','%')
Will become back
2C%E3%80%90%E5%BD%A2%E3%80%91%E6%97%A0%E7%A2%8D%E7%9A%84%E3%80%82
