String#scrub!

str.scrub! → str
str.scrub!(repl) → str
str.scrub!{|bytes|} → str

If the string is invalid byte sequence then replace invalid bytes with given replacement character, else returns self. If block is given, replace invalid bytes with returned value of the block.

Example
"abc\u3042\x81".scrub! #=> "abc\u3042\uFFFD"
"abc\u3042\x81".scrub!("*") #=> "abc\u3042*"
"abc\u3042\xE3\x80".scrub!{|bytes| '<'+bytes.unpack1('H*')+'>' } #=> "abc\u3042<e380>"
