The Digital Ghost in the Machine: Understanding Text Encoding and “Mojibake”

Have you ever opened an email, a database export, or a downloaded text file only to be greeted by a chaotic wall of symbols like सॊता? Far from being an encrypted secret code or an alien language, this phenomenon is a classic example of Mojibake (character transformation)—a digital miscommunication that occurs when text is interpreted using the wrong character encoding.

What is Mojibake?

The word Mojibake originates from Japanese (moji, meaning character or letter, and bake, meaning to transform or turn into). It happens when computers lose track of a file’s dictionary.

At their core, computers do not understand letters, punctuation marks, or emojis; they only store raw numbers (bytes). A character encoding functions like a translation dictionary, instructing the computer on which visual glyph corresponds to a specific byte value.
