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:

Any suggestions how to do that?
