vb.net: Do I have any control of the encoding used to send plain text
messages. Using System.Net.Mail the source shows the
Content-Transfer-Encoding as quoted-printable; Using System.Web.Mail
the source shows the Content-Transfer-Encoding as 7bit. A pdf
attachment is encoded with base64 for both. My big concern is
assuring that some of our 200 plus residence do not get odd looking
characters in the community email we send. Several use Macs, many web
mail, a few Thunderbird and many OE and Outlook. We have had problem
sending via Comcast Web mail.

Ed,

As long as you use true ASCII (the first 7 bits of every code page), then
you will only have problems if the other side is expecting not the basic 26
characters of most West European languages (in upper and lower) characters
and modern Arabian cifers.
However then never sent your messages as HTML because that is controled by
the client computer.

What PDF is doing with a document is not under your control, however they
have made it to be showed exactly as the maker created it.
