Email subject line garbled

4.5

The subject contains weird characters like "=?UTF-8?B?..." instead of text.

Symptoms
  • Unreadable subject
  • Code in title
  • Foreign characters
Possible Causes
  • Encoding mismatch
  • Old mail client
  • Non-standard characters

Step-by-Step Fix

1

Change Encoding to UTF-8

In settings, ensure "Unicode (UTF-8)" is the default for all mail.

2

Update App

Modern apps handle complex subject line encoding much better.

3

Check Sender

If only one person's mail is garbled, their system is likely misconfigured.

When to See a Technician

This is usually a "MIME" encoding issue where the subject wasn't properly converted to plain text.
