What coding is used in this string?

My app is downloading eMails from a POP3 server. But it receives "strange" subject lines. I see there is a pattern of coding in there. But what exactly is that coding? What do I google for if I want cover the parsing of lines like that?

=?utf-8?Q?HMS=20will=20no=20longer=20provide=20Netbiter=20SIM=2Dcards?=

The eMail header is:

Subject: =?utf-8?Q?HMS=20will=20no=20longer=20provide=20Netbiter=20SIM=2Dcards?=

So I know it's coded by the sender. Also this is just one of many header lines, which all seem to be valid. The subject is obviously HMS will no longer provide Netbiter SIM-cards after you replace "=20" with spaces and all the other stuff. The eMail is just a notification from a supplier.

**Found it myself:** [RFC 2047][1]

I don't remember exactly but i have experienced a issue like this before. If the subject is greater than some length of character (which i think is 75 chars) then subject will not be parsed properly.

This used to be a problem in codeIgniter (I don't use it now, so don't know the current status of this issue)

To resolve this issue you might have to change your email config.

There might be other reasons for this issue but i think this is because you have more characters in your subject.
