when I have a document open in Word, and I email it directly from Word, this works fine as long as my default email client is Outlook.

But if I use any other email client, I run into problems when the file name is in Hebrew. The file name is not rendered correctly, and comes out in meaningless characters, like this: ׳›׳•׳×׳¨׳•׳× ׳ ׳*׳’׳ ׳™׳×.doc

This issue arises only when emailing directly from Word.
If I save the file to my desktop, and right-click it, and choose send to/mail recipient, the file name is rendered correctly.
