Problems with charset gb2312 and mime headers

[Jens Ahlin]

Hi,

I have seen this happen sporadically but with charset ISO8859-1 encoded
subject line. The client is a Outlook 2003 client. This does not happen
often and I cannot se any pattern in the behaviour. I only notice this
when the subject line contains swedish charchters.

Any ideas ?
