Python2.7：字符转UFT-8、GBK、BIG5并得到bytes

# encoding: utf-8

def hexstr(s):
    return ''.join([hex(ord(c)).replace('0x','\\x') for c in s])

# 转big5
def toBig5(s):
    s1 = s.decode('utf-8')  
    lis = []
    for e in list(s1):
        try:
            lis.append(e.encode('big5'))
        except:
            lis.append('&#%d;' % ord(e))
    return hexstr(''.join(lis))

# 转utf-8
def toUtf8(s):
    s1 = s.decode('utf-8')  
    lis = []
    for e in list(s1):
        lis.append(e.encode('utf-8'))
    return hexstr(''.join(lis))

# 转gbk
def toGbk(s):
    s1 = s.decode('utf-8')  
    lis = []
    for e in list(s1):
        lis.append(e.encode('gbk'))
    return hexstr(''.join(lis))
