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

See more MIME Examples

Demonstrates how setting the Charset property controls the character encoding used for the text body in a MIME message. B4X

'  This example assumes the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim mime As ChilkatMime
mime.Initialize

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

'  Set the Content-Type
mime.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.
mime.Encoding = "quoted-printable"

'  Set the Charset to utf-8
mime.Charset = "utf-8"

'  Examine the MIME:
Log(mime.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";
mime.Charset = "iso-8859-1"

'  Get the MIME again...
Log(mime.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
