Do you know whether BASE64 was considered as encoding scheme and
whether uuencode was preferred?

BASE64 is well standardized and generally used in MIME email
(http://www.mhonarc.org/~ehood/MIME/2045/rfc2045.html#6.8) to encode
binary data. There are plenty of codecs floating around.

I remember reading this in the mmencode(1) man-page:

    RATIONALE
    
    Mimencode is intended to be a replacement for uuencode for mail
    and news use. The reason is simple: uuencode doesn't work very
    well in a number of circumstances and ways. In particular,
    uuencode uses characters that don't translate well across all mail
    gateways (particularly ASCII <-> EBCDIC gateways). Also, uuencode
    is not standard -- there are several variants floating around,
    encoding and decoding things in different and incompatible ways,
    with no "standard" on which to base an implementation. [...]

Best regards,
Marcus
