#destination_encoding ⇒ String

Returns the destination encoding as an encoding object.

Returns:

# File 'transcode.c', line 4283

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

#destination_encoding_name ⇒ String

Returns the destination encoding name as a string.

Returns:

4274
4275
 
# File 'transcode.c', line 4271

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

#error_char ⇒ String

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 4304

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

#source_encoding ⇒ Encoding

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
