Special character character set

  • Is iso-8859-1 the correct subset of utf-8?
  • What about iso-8859-n?
  • What about windows-1252?

If the answer does not match any of the above, what are the disjoint characters? I am testing some logic that detects encodings and wants to write tests to verify that the detection works correctly.

Is iso-8859-1 the correct subset of utf-8?

The ISO-8859-1 personal report (the first 256 Unicode characters) is the correct subset for UTF-8 (each Unicode character).

However, the characters U + 0080 to U + 00FF are encoded differently in two encodings.

  • ISO-8859-1 80 FF.
  • UTF-8 , C2 80 - C3 BF.
