garbled display of messages with charset x-gbk

[phyrster <phyrster@xxxxxxxxx>]

hi mutters in mud,

Please refer to the attachment for a message that can't be displayed
correctly in mutt.

I have already have one line like this:

| charset-hook ^us-ascii$ gb2312

in my .muttrc and the message's charset seems to be x-gbk. How to edit this
charset-hook line and make the message display correctly?

And what does ^  and  $ mean as in "charset-hook ^us-ascii$ gb2312"?

regards

bxuef
