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.
