Non-standard characters when using Send Email (HTML Formatted)

Hi there

I'm trying to figure out a way to use the Send Email (HTML-formatted) script and preserve the special characters in the message body. As far as I can see, the other ScriptMaster email scripts all include a parameter to set character set as UTF-8... but for some reason the HTML script doesn't.

Is there a simple way around this? I do need the emails to be HTML.

Curiously, emails sent via this method always have  a header which includes "charset=Windows-1252". Not sure where that's set, but I'm guessing if I could find that out, I'd be half way home.

Hope someone can help, but apologies in advance, if the solution involves more than a superficial understanding of how the ScriptMaster functions setup works: I've really only got it to work (minus the character set issue) by trial and error. ScriptMaster, mail.jar and Groovy are pretty much black boxes to me, I'm afraid!

Cheers

Jon
