#destination_encodingString

Returns the destination encoding as an encoding object.

Returns:

# File 'transcode.c', line 4260

static VALUE
ecerr_destination_encoding(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding"));
}

#destination_encoding_nameString

Returns the destination encoding name as a string.

Returns:

# File 'transcode.c', line 4248

static VALUE
ecerr_destination_encoding_name(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding_name"));
}

#error_charString

Returns the one-character string which cause Encoding::UndefinedConversionError.

ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP")
begin
  ec.convert("\xa0")
rescue Encoding::UndefinedConversionError
  puts $!.error_char.dump   #=> "\xC2\xA0"
  p $!.error_char.encoding  #=> #<Encoding:UTF-8>
end

Returns:

# File 'transcode.c', line 4281

static VALUE
ecerr_error_char(VALUE self)
{
    return rb_attr_get(self, rb_intern("error_char"));
}

#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
