(PowerShell) 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.

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

$mime = New-Object Chilkat.Mime

# 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:
$($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...
$($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
