Each character displays its Unicode code point (e.g., U+0041), decimal value, binary representation, and whether it's ASCII or non-ASCII.
Yes. The tool identifies characters that may cause encoding problems, including replacement characters (U+FFFD), control characters, and ambiguous encoding.
Yes. Every character shows its full Unicode code point (U+XXXX), name, and category (letter, number, symbol, etc.).
Yes. ASCII (0x00-0x7F) and non-ASCII characters are clearly labeled. Non-ASCII characters are highlighted for easy identification.
