- The number of bytes of data to be encoded.
- The length in characters of the character set to use for the conversion.
The number of characters required for a buffer that could hold encoded data of nSrcLen bytes.
The "B" encoding scheme is described in RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt).
