Escape characters are essential in JSON whenever special characters appear inside string values and would otherwise break the syntax.
Why escaping exists
JSON strings are wrapped in double quotes, so any quote that appears inside the value must be escaped to avoid ending the string early.
The same logic applies to backslashes and certain control characters.
Where it goes wrong
Escaping errors often appear when developers manually build JSON strings inside code, logs, or templates.
One missing backslash can turn valid content into invalid JSON instantly.
Safer way to handle it
Whenever possible, let a serializer or trusted library generate JSON strings instead of manually escaping everything yourself.
That reduces fragile edge cases and keeps payload generation more reliable.
