我可以设置AppleScript创建的电子邮件的编码吗？

Question

I have to send a mailing list and want to use Apple Mail for this. I have created a script that reads a UTF8 encoded text file and uses this text to set the contents of the e-mail message. This text is in variable thisText. The code importing the text is similar to

set fileHandle to open for access theFile
set mailText to (read fileHandle) as «class utf8»
close access fileHandle

After this, I make small adjustments to the text for each recipient and prepare the e-mails with the following code:

using terms from application "Mail"
  tell application "Mail"
    set theAccount to "Economy-x-Talk Support"
    set theNewMessage to make new outgoing message with properties ¬
       {account:theAccount, subject:thisSubject, content:thisText, visible:false}
    tell theNewMessage
      make new to recipient at end with properties {address:thisEmail}
      set sender to "Economy-x-Talk Support <xxx@xxxxxxxx.com>"
    end tell
  end tell
end using terms from

The problem is that if the text contains special characters, Mail displays them incorrectly. I believe that Mail doesn't understand that the encoding of the message is UTF8. Is there a way to define the encoding of a message when making it? something like:

properties {encoding:utf8}

perhaps? I tried this and it didn't work. I was unable to find the answer elsewhere.

我发现有关此功能是否有效的冲突信息，但是尝试使用以下终端命令更改默认邮件编码：

defaults write com.apple.mail NSPreferredMailCharset "UTF-8"
