TextLimit guides
Bytes versus characters.
A character is what a person sees. A byte is how much space the encoded text takes. Those are not always the same.

ASCII is simple
Basic English letters, digits, and common punctuation usually use one UTF-8 byte each. That makes character count and byte count feel similar for plain text.
Unicode adds detail
Accented letters, non-Latin scripts, emoji, and combined marks can use multiple bytes. A short-looking string can exceed a byte limit even when the character count looks fine.
Where byte limits appear
APIs, databases, CSV imports, SMS gateways, and older forms may enforce byte limits. TextLimit shows UTF-8 bytes so developers and operators can catch that mismatch before submission.
When byte count matters
- Check UTF-8 bytes for API payloads and database fields.
- Watch emoji and non-English text when a system has strict storage limits.
- Use byte count and character count together for copied text.
- Test the exact text, not a simplified draft.
