Character encoding is a system that tells computers how to represent letters, numbers, symbols, and special characters as bytes (zeros and ones). Without proper encoding, characters like '�' or '�' may display incorrectly. Common encodings include UTF-8, ISO-8859-1 (Latin-1), and Windows-1252.

A BOM is a special marker at the beginning of a file that indicates the file uses Unicode and, for UTF-16/UTF-32, the byte order (big-endian or little-endian). It helps software correctly interpret the text. UTF-8 BOM is optional but can assist programs in recognizing UTF-8 encoded files.

The tool can detect UTF-8, ISO-8859-1 (Latin-1), Windows-1252, and other common encodings.

Yes, it shows whether the text is valid UTF-8 and flags any invalid byte sequences.

Absolutely. By identifying the correct encoding and BOM, you can prevent problems like misrepresented accented letters or corrupted characters.
