The spam filtering does a pretty decent job in capturing most unwanted email.

However, if you are looking at the spam report (From and Subject headers at the beginning of a report) it is becoming increasingly difficult to determine whether something may actually be important.

This is because a high percentage of this header information is encoded in "utf-8" format and unreadable.

Since these headers are extracted from the full header of the email, it should be possible to decode this information as it is extracted and display it in a readable form.
