python3 Unicode字符与16进制编码互转（单个字符）

def pad(text):
    while len(text) % 4 != 0:
        text = '0'+text
    return text

def Unicode2HexChar(Unicde_Char):#Unicode转16进制
    Hex_Char = ""
    for i in range(0, len(Unicde_Char)):
        Hex_Char += (hex(ord(Unicde_Char[i])).replace('0x','').zfill(4))
    return Hex_Char

print(Unicode2HexChar('。'))

def HexChar2Unicode(Hex_Char):#16进制转Unicode
    Unicode_Char=''
    if len(Hex_Char)>8:#Unicode编码不能超过8位
        return None
    if len(Hex_Char)==4:
        Unicode_Char='\\u'+Hex_Char
    if len(Hex_Char)<4:
        Unicode_Char='\\u'+pad(Hex_Char)
    if len(Hex_Char)>4:
        Unicode_Char='\\U'+pad(Hex_Char)
    return Unicode_Char.encode().decode('unicode_escape')

print(HexChar2Unicode('ADA'))

def chineseToUnic(ch):#中文字符转16进制
    return ch.encode('unicode_escape')[2:].decode('utf-8')

print(chineseToUnic('飓'))
