[quote user="Thomas R. Stephenson"]... use UTF-8 all the time and it will be able to handle your mixing of plain text and high bit characters.[/quote]
I changed Pegasus advanced settings to UTF-8 charset and forwarded the offending document to myself. The subject line still contained â€“. Then I noticed that the dash in the original email (in Pegasus) was longer than usual so I replaced it with a normal -. Now the dash displays correctly. As you say, I must have pasted the original from Word.
