Quoted Printable Equals Sign Token Tool

Description

Require symbol exactly = and return token =3D.

Quoted-printable body encoding represents selected octets with equals-sign hexadecimal escapes and treats line endings and trailing whitespace specially. Fixing one escape or trailing run does not perform all MIME body transformations.

Require symbol exactly = and return token =3D.

When to use this tool

Use Quoted Printable Equals Sign Token when checking one quoted-printable literal or trailing-whitespace transformation.

How to use the tool and how it works

Enter symbol. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read token. Use the output convention below.

Require symbol exactly = and return token =3D.^[1]

Quoted-printable has specific escape and trailing-whitespace rules. This transformation covers only the stated fragment, not complete MIME body encoding.^[2]

Input field	Meaning and units	Accepted input
symbol	Symbol	Required. Text; maximum UTF-16 length 8192.

Output field	Interpretation	Returned shape
token	Token	Required. Text; maximum UTF-16 length 8192.

  "input": {

  },
  "output": {
    "token": "=3D"
  }
}

Limitations and assumptions

This emits one quoted-printable escape, not a full encoder or decoder; MIME encoded-word Q and body quoted-printable have different additional rules.
Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Use a complete MIME body encoder when byte conversion, line-length limits and soft line breaks matter.
