How it works
A browser-side transform that reports invalid input instead of silently changing it
- Start with the included valid sample, then replace it with your own input.
- Review errors and compare the output before replacing source data.

Common Mistakes to Avoid
Common Mistakes to Avoid
Confusing code point with byte encoding
U+1F389 is the code point (abstract number). Its UTF-8 encoding is 4 bytes (F0 9F 8E 89). Its UTF-16 encoding is a surrogate pair (D83C DF89). The same character has different byte representations.
Using string.length to count characters
In JavaScript/Java, string.length counts UTF-16 code units, not characters. A supplementary character (emoji) counts as 2. Use [...str].length or Intl.Segmenter for true character count.
