Switch between text and character codes
Expand text into codes
Paste Korean text, emoji or whitespace in Text to codes. The character table can reveal differences between strings that look identical.
Match the incoming notation
For Codes to text, choose the format used by your input: \uXXXX, U+XXXX, HTML numeric entities or UTF-8 hex bytes.
Read offsets and byte sizes
Offsets start at zero and use UTF-16. A whitespace or combining-mark label is a clue to inspect, not proof that the character is wrong.
