Sorry if something goes wrong, it is my first post.

This is really bizarre. For some, not all, e-mails I receive, in the senders' signature, Outlook 2007 shows this:


The senders do not change their font and the rest of the text is fine.
Note the character string which is reversed ?

I have tried to edit the e-mail, select the few lines like above and changed the font.
Outlook does not refuse the font change, but regardless of the font I specify, it does not change the characters. (It will show Arial but still display the weird characters)

I have copied and pasted the text in Word, same behavior from Word.

Then I pasted Unformatted and got the second line where the characters are backward.

Did anyone see such behavior ?
Where should I look to find the problem and correct ?

Thanks
