Hallo Everyone, I have a question: I want to implement an attachment filter ( mime_header_checks ), that filters special unicode "Format characters". Examples: 0x202E (right-to-left override) 0x202B (right-to-left embedding) 0x202D (left-to-right override) 0x202A (left-to-right embedding)
Complete list here (page 4): http://www.unicode.org/charts/PDF/U2000.pdf (page 4) You can look the reason up here: http://www.h-online.com/security/news/item/Backwards-Unicode-names-hides-malware-and-viruses-1242114.html Any suggestions how to do that?
