Jin Daily Tech Trivia - Why are there ”=” signs in the Epstein emails?

Recently, the US released a large batch of Jeffrey Epstein’s emails, and unsurprisingly, there has been a lot of drama around the tech industry and alleged crime networks.

Why do some of these emails contain random ”=” signs? And why do they sometimes look like they are missing a character? Are those secret code for a more sinister thing?

So I dug into it.

Email systems commonly used a MIME encoding called quoted-printable for non HTML encoding email

Quoted-printable exists for two main reasons:

Force non-ASCII characters into ASCII-safe representations Ensure no line exceeds 76 characters When a line is too long, the MIME format inserts a soft line break using: =\r\n

That tells the email client, “This line continues on the next line.”

Here is where things get messy.

The emails obtained by the FBI were likely reviewed and redacted the content using Windows-based tools. Many Windows text-processing tools handle quoted-printable encoding poorly. When they encounter =\r\n, they sometimes treat it as an error.

Instead of correctly rejoining the line, they:

Remove \r\n Keep the =

Accidentally drop the next character

Example:

I ate=\r\n pizza Processed correctly: I ate pizza

But:

confiden=\r\ntial Processed badly: confiden=ial

The parser sees =\r\n as invalid, removes the line break, and eats one character along the way.

That is how you end up with mysterious ”=” signs scattered throughout the emails.

This is a real-world example of the infamous CRLF problem, a text encoding issue that has haunted operating systems since the early days.

For reference: Modern Mac or Unix: \n Classic Mac: \r Windows: \r\n
