如何：扭曲 privmsg 以接受非 ascii 字符串
我有一个用 python 编写的 IRC 机器人，使用 Twisted。
它可以打印非 ASCII 字符串，而不会出现 self.msg(channel, str.encode('utf-8') 的问题。
但是，当使用 接收非 ASCII 字符串时，我会遇到异常privmsg：
def privmsg(self, user, channel, msg):
msg = msg.encode('utf-8')
user = user.split('!', 1)[0]
[... code goes here...]
我收到以下异常：
File "/usr/lib64/python2.4/site-packages/twisted/words/protocols/irc.py", line 1498, in handleCommand
method(prefix, params)
File "/usr/lib64/python2.4/site-packages/twisted/words/protocols/irc.py", line 1043, in irc_PRIVMSG
self.privmsg(user, channel, message)
File "./IlyBot.py", line 58, in privmsg
msg = msg.encode('utf-8')
exceptions.UnicodeDecodeError: 'ascii' codec can't decode byte 0xd1 in position 4: ordinal not in range(128)
有谁知道如何在 privmsg 收到的消息上强制编码为 UTF-8？
I have an IRC bot written in python that uses Twisted.
It can print non-ascii strings without a problem with self.msg(channel, str.encode('utf-8').
However, I get exceptions when a non-ascii string is being received with privmsg:
def privmsg(self, user, channel, msg):
msg = msg.encode('utf-8')
user = user.split('!', 1)[0]
[... code goes here...]
I get the following exception:
File "/usr/lib64/python2.4/site-packages/twisted/words/protocols/irc.py", line 1498, in handleCommand
method(prefix, params)
File "/usr/lib64/python2.4/site-packages/twisted/words/protocols/irc.py", line 1043, in irc_PRIVMSG
self.privmsg(user, channel, message)
File "./IlyBot.py", line 58, in privmsg
msg = msg.encode('utf-8')
exceptions.UnicodeDecodeError: 'ascii' codec can't decode byte 0xd1 in position 4: ordinal not in range(128)
Does anyone know how to force the encoding to be UTF-8 on the msg received by privmsg?

我认为你想要“解码”，而不是“编码”。
privmsg的参数是一个字节字符串（str，在 python 2.x 中），因此如果您希望它是文本，则必须de-对这些字节进行编码。您不能强制编码为 UTF-8，因为编码是您从服务器接收到的编码。由于 IRC 完全缺乏字符集支持，这是您能做的最好的事情。
I think you want "decode", not "encode". The argument to
privmsgis a byte string (str, in python 2.x), so if you want it to be text you have to de-code those bytes.You can't force the encoding to be UTF-8, because the encoding is whatever you happened to receive from the server. Thanks to IRC's complete lack of character set support, that's the best you can do.
