}

#error_bytesString

Returns the discarded bytes when Encoding::InvalidByteSequenceError occurs.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")
begin
  ec.convert("abc\xA1\xFFdef")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "\xFF" on EUC-JP>
  puts $!.error_bytes.dump          #=> "\xA1"
  puts $!.readagain_bytes.dump      #=> "\xFF"
end

ecerr_error_bytes(VALUE self)
{
    return rb_attr_get(self, rb_intern("error_bytes"));
}

#incomplete_input?Boolean

Returns true if the invalid byte sequence error is caused by premature end of string.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")

begin
  ec.convert("abc\xA1z")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "z" on EUC-JP>
  p $!.incomplete_input?    #=> false
end

begin
  ec.convert("abc\xA1")
  ec.finish
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: incomplete "\xA1" on EUC-JP>
  p $!.incomplete_input?    #=> true
end

#source_encodingEncoding

Returns the source encoding as an encoding object.

Note that the result may not be equal to the source encoding of the encoding converter if the conversion has multiple steps.

ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") # ISO-8859-1 -> UTF-8 -> EUC-JP
begin
  ec.convert("\xa0") # NO-BREAK SPACE, which is available in UTF-8 but not in EUC-JP.
rescue Encoding::UndefinedConversionError
  p $!.source_encoding              #=> #<Encoding:UTF-8>
  p $!.destination_encoding         #=> #<Encoding:EUC-JP>
  p $!.source_encoding_name         #=> "UTF-8"
  p $!.destination_encoding_name    #=> "EUC-JP"
end
