UTF-8 Encoder

Convert text to UTF-8 byte array representation (decimal values).

💡 About UTF-8 Encoding

UTF-8 encoding shows how JavaScript strings are represented as bytes internally.

Common use cases:

  • Understanding string byte sizes for APIs
  • Debugging character encoding issues
  • Working with binary protocols
  • File size calculations for text data

Note: Each number represents one byte (0-255). Unicode characters may use multiple bytes.
