Frequently Asked Questions

What character data is shown?

Each character displays its Unicode code point (e.g., U+0041), decimal value, binary representation, and whether it's ASCII or non-ASCII.

Does it detect encoding issues?

Yes. The tool identifies characters that may cause encoding problems, including replacement characters (U+FFFD), control characters, and ambiguous encoding.

Can I see Unicode code points?

Yes. Every character shows its full Unicode code point (U+XXXX), name, and category (letter, number, symbol, etc.).

Does it identify non-ASCII characters?

Yes. ASCII (0x00-0x7F) and non-ASCII characters are clearly labeled. Non-ASCII characters are highlighted for easy identification.

When using Character Encoding Converter, is my text uploaded?

No. All analysis happens locally in your browser. No text data is transmitted to any server.
