UTF-16 Notes
• UTF-16 stores data as 16-bit code units.
• Characters in the Basic Multilingual Plane normally use one code unit.
• Characters above U+FFFF use two UTF-16 code units called a surrogate pair.
• JavaScript string.length counts UTF-16 code units, not Unicode code points.
• For example, 😀 is one Unicode code point but two UTF-16 code units.
• Each UTF-16 code unit occupies 2 bytes.
• The inspection is performed entirely in the browser.

What is UTF-16 Inspector?

Inspect UTF-16 representations of text by examining Unicode characters, code points and the hexadecimal code units used to represent them.

How to use

  1. Enter or paste text.
  2. Inspect the Unicode characters.
  3. Review the UTF-16 code units.
  4. Copy the inspection results.
