I have a user who when sending an e-mail with for example "can't" it
will send okay and appear okay in his Sent Items.

However when someone replies and you read his original message in the
e-mail history. "Can't" now appears as "Can?t"

Sounds like a disagreement in the Windows encoding used. The sender and
receiver should compare their settings in ToolsOptionsMail FormatFonts
and International Options.
