decode_b(str) public

Decodes text formatted using a subset of RFC2047 (the one used for mime-encoding mail headers).

Only supports an encoding type of ‘b’ (base 64), and only supports the character sets ISO-2022-JP and SHIFT_JIS (so the only two encoded word sequences recognized are =?ISO-2022-JP?B?...= and =?SHIFT_JIS?B?...=). Recognition of these sequences is case insensitive.
