UTF-16 Code Unit Converter
Represent a JavaScript string as uppercase four-digit UTF-16 code units, preserving surrogate pairs as two units.
Description
Represent a JavaScript string as uppercase four-digit UTF-16 code units, preserving surrogate pairs as two units.
UTF-16 Code Unit Converter converts entered text using one explicit character or encoding convention. Represent a JavaScript string as uppercase four-digit UTF-16 code units, preserving surrogate pairs as two units.1
When to use UTF-16 Code Unit Converter
Use this tool when a protocol, document format, diagnostic task, or learning exercise needs the exact textual representation produced by this encoding.
How UTF-16 Code Unit Converter works
Represent a JavaScript string as uppercase four-digit UTF-16 code units, preserving surrogate pairs as two units.1
How the conversion processes text
- Read the entered string as Unicode text without silently trimming it.
- Apply the named byte or character representation in input order.
- Return one copyable string and preserve unsupported input where the contract says no mapping exists.
Limitations and assumptions
- The tool operates on the exact entered Unicode string; normalization, whitespace, and line endings can change the result.
- A textual encoding is not encryption and does not conceal sensitive information.
- Interoperating systems must use the same character encoding and variant rules to reproduce the output.
Alternative or Complementary approaches
Use the inverse decoder when round-trip recovery is required, and use encryption rather than encoding when confidentiality is the goal.
