Yes, I see. But my previous searches makes me think that without special instructions filter matches only the part of the header before the first "new line", which is right after "?=". Is it wrong for decoding Base64 and related only to the regex matching, so the part after "new line" breaks decoding from Base64? If so, is there a way to workaround this situation?
