ASCII and Unicode Code Point Lookup

This ASCII table lists decimal, hex, octal, binary, and HTML entity forms for characters so you can look up control codes, punctuation, and Unicode points without leaving the browser.

Search by character or code. Use it when debugging encoding bugs, writing escape sequences, or checking what a byte means in a log dump. The HTML entities tool is better when you only need encode/decode.

Tips

  • ASCII is 0–127. Bytes 128–255 are not ASCII — they depend on the encoding (Latin-1, UTF-8, Windows-1252).
  • Copy the HTML entity when you need a character that is awkward to type.
  • Newline is decimal 10 (LF) or 13 (CR). Mixed line endings are a common source of “invisible” diffs.
