About these encodings
  • ASCII positions run from 0 to 127. Position cards show the decimal byte value followed by hexadecimal.
  • “Extended ASCII” is not a single encoding. ISO-8859-1 (Latin-1) and Windows-1252 are shown separately; they differ at bytes 128–159. Windows-1252 leaves five of those bytes undefined.
  • Legacy position cards appear only when the character has an exact mapping. For example, the euro sign is Windows-1252 byte 128 (0x80), but has no ASCII or Latin-1 position. A legacy byte is not necessarily the Unicode code point or its UTF-8 encoding.
  • Percent encoding lists every UTF-8 byte; URL-safe characters do not normally need encoding.
  • JSON escapes omit the surrounding quotes.
  • UTF code units are not byte-order-specific.
  • HTML parsers remap numeric references for U+0000 and some control characters, so these may not round-trip.
