The local-part of the email address may use any of these ASCII characters RFC 
5322 Section 3.2.3:

    Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
    Digits 0 to 9 (ASCII: 48-57)
    Characters !#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 
94-96, 123-126)
    Character . (dot, period, full stop) (ASCII: 46) provided that it is not 
the first or last character, and provided also that it does not appear two or 
more times consecutively (e.g. John..Doe at example.com is not allowed.).
    Special characters are allowed with restrictions including:
        Space and "(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 
91-93)

The restrictions for special characters are that they must be contained 
between quotation marks and that 3 special chars (The space, backslash \ and 
quotation mark " (ASCII: 32, 92, 34) must be preceded by a backslash \ (e.g. 
"\"\\\ ").
 
Cheers,
