Guide / 02
Quick guide
- Paste the exact text you plan to submit into the text area.
- Choose the relevant measure: characters, characters without spaces, words, lines, or UTF-8 bytes.
- Edit the text while watching the counters update until the required limit is met.
CHECK
Validate the result
Enter A and the Korean character 가 as a quick check: they each count as one character, while their UTF-8 sizes are one and three bytes respectively.
LIMITS
Know the limits
Characters are counted as Unicode code points, so a combined emoji may count as more than one even when it looks like a single symbol. Words are separated by whitespace rather than linguistic rules.

FAQ
Frequently asked
Why is the byte count larger than the character count?
UTF-8 uses a variable number of bytes per character. ASCII usually takes one byte, while many accented letters, CJK characters, and emoji require multiple bytes.
