I was wondering if you had an VB.NET example of the creation of an email with both an html
and text mime part where the parts are not UUEncoded (base64) or is there a reason that they should be?
One note: UUEncoding is an entirely different encoding than Base 64, so I take your question to be:
"Why does Chilkat choose Base64 encoding?".
The answer is that it only chooses Base-64 encoding in certain circumstances.
Binary attachments such as GIF and JPEG images are certainly Base64 encoded.
Chilkat will choose Base64 for Asian text (Chinese, Japanese, Korean, etc.) because
this is usually the most compact method of encoding. For European languages with
accented characters (diacritics) quoted-printable encoding is used. If an email contains
text such that all characters are us-ascii, then plain-text encoding is used (i.e. no encoding.)
