Setting the MIME Text Charset (such as utf-8, iso-8859-1, etc.)

Demonstrates how setting the Charset property controls the character encoding used for the text body in a MIME message.

*  Set the MIME body using some 8bit non-us-ascii characters:
loMime.SetBody("á, é, í, ó, ú")

*  Set the Content-Type
loMime.ContentType = "text/plain"

*  Set the Content-Transfer-Encoding to "quoted-printable"
*  so it's easy to see the bytes used to encode each character
*  (i.e. it will be easy to see that utf-8 uses 2-bytes for
*  non-us-ascii characters such as "á", whereas a character
*  encoding such as iso-8859-1 will use one byte per character.
loMime.Encoding = "quoted-printable"

*  Set the Charset to utf-8
loMime.Charset = "utf-8"

*  Examine the MIME:
? loMime.GetMime()

*  The MIME should look like this:
*  
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8"

=C3=A1, =C3=A9, =C3=AD, =C3=B3, =C3=BA

*  Now change the Charset to "iso-8859-1"
loMime.Charset = "iso-8859-1"

*  Get the MIME again...
? loMime.GetMime()

*  Now the MIME should look like this:
*  
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="iso-8859-1"

=E1, =E9, =ED, =F3, =FA
