Parent:
rb_eEncodingError

Raised by Encoding and String methods when a transcoding operation fails.

Public Instance Methods

destination_encoding → string Show source
static VALUE
ecerr_destination_encoding(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding"));
}

Returns the destination encoding as an encoding object.

destination_encoding_name → string Show source
static VALUE
ecerr_destination_encoding_name(VALUE self)
{
    return rb_attr_get(self, rb_intern("destination_encoding_name"));
}

Returns the destination encoding name as a string.

error_char → string Show source
static VALUE
ecerr_error_char(VALUE self)
{
    return rb_attr_get(self, rb_intern("error_char"));
}

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
source_encoding → encoding Show source
static VALUE
ecerr_source_encoding(VALUE self)
{
    return rb_attr_get(self, rb_intern("source_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
source_encoding_name → string Show source
static VALUE
ecerr_source_encoding_name(VALUE self)
{
    return rb_attr_get(self, rb_intern("source_encoding_name"));
}

Returns the source encoding name as a string.
