Frequently Asked Questions

Why do Korean characters use more bytes than characters?

In UTF-8, Korean characters usually take multiple bytes, so character limits and byte limits can differ.

Can I check whether I exceed a byte limit?

Yes. Enter a limit to see current bytes, remaining bytes, and overage.

Does this use UTF-8?

Yes. Byte length is calculated with UTF-8, which is common for web input fields.
