[ruby-core:56073] Re: [ruby-trunk - Bug #8653][Open] Unexpected result of String#succ with utf-16 and utf-32 string.

I don't say the bahavior is incorrect.

  % ruby -e 'p "A".encode("UTF-16LE").force_encoding("ASCII-8BIT")'
  "A\x00"
  % ruby -e 'p "A".encode("UTF-16LE").succ.force_encoding("ASCII-8BIT")'
  "A\x01"
  % ruby -e 'p "B".encode("UTF-16LE").force_encoding("ASCII-8BIT")'
  "B\x00"
  % ruby -e 'p "B".encode("UTF-16LE").succ.force_encoding("ASCII-8BIT")'
  "B\x01"

String#succ generates the bytewise lexicographicaly next characters
successfully.

I agree that is not intuitive.
But it is very difficult to define String#succ in encoding neutral way.
