Why does Evolution not display exotic characters in received emails?
This often happens in plain text emails, words like “compaƱeros” or “ber” are displayed “compaeros” and “ber”, also in the email source. This happens because the offending messages do not include information about the character encoding used because they are sent by broken email programs. Change the character encoding from “Unicode” to (for example) “Western European” by choosing “View | Character Encoding” from the main menu. You have to make this change every time you view the message.
