Why byte size matters
APIs, databases, and caches often enforce byte limits. A string can fit in character count but exceed the byte limit, especially with emoji or accented characters.
How the count works
We encode the text as UTF-8 and report the total byte length. This matches how most web systems measure payload size.
Typical use cases
- API and webhook payload limits
- Database column size checks
- SMS, push notification, and metadata limits
Tips
- Watch for emojis and special characters in tight byte budgets.
- Keep a safety buffer for JSON or metadata wrappers.
