Solution 1:

It seems that you can set Content-Transfer-Encoding: base64 quote from W3C:

Each part may be encoded and the "Content-Transfer-Encoding" header supplied if the value of that part does not conform to the default (7BIT) encoding

Provided your Java Web Server in use doesn't ingore parameter Content-Transfer-Encoding.
