Returns the character set of the email. Returns nil if no encoding set or returns whatever default you pass as a parameter - note passing the parameter does NOT change the mail object in any way.

Example:

mail = TMail::Mail.load("path_to/utf8_email")
mail.charset #=> "UTF-8"

mail = TMail::Mail.new
mail.charset #=> nil
mail.charset("US-ASCII") #=> "US-ASCII"

def charset( default = nil )
  if h = @header['content-type']
    h['charset'] or default
  else
    default
  end
