A PrintableString is a Universal Tag in the ASN.1 notation.

According to RFC 3280 [1], PrintableString is an acceptable character set for the DirectoryName data type. PrintableString supports a subset of characters which does not include the "at sign" or "ampersand" (@). This often causes problems for implementers when they attempt to place an email address within an X.509 digital certificate distinguished name.

According to the Layman's Guide to a Subset of ASN.1, BER, and DER [2], the character set of PrintableString can be expressed as:

A, B, ..., Z
a, b, ..., z
0, 1, ..., 9
(space) ' ( ) + , - . / : = ?
