Hello! You can check in the options-> Show->; Format->; Font, choose the appropriate font. If it still doesn't work, you can right-click on the sent email and select the attribute, and then select the appropriate character encoding in the default character encoding item, which should solve the problem of garbled code. If a folder, such as an inbox, also appears the situation that the received mail is garbled, it is also set in this way. I hope I can help you!
