高野です。

## 以下のFailについてです。

1. Failure:  
test\_errors(TestTranscode)  
[/home/takano/ruby/test/fileutils/fileasserts.rb:8:in `_wrap_assertion' /home/takano/ruby/test/fileutils/fileasserts.rb:8:in`\_wrap\_assertion’  
/home/takano/ruby/test/ruby/test\_transcode.rb:22:in `test\_errors’]:  
 exception expected but none was thrown.

* * *

## 22行目はこんな感じです。

## assert\_raise(ArgumentError) { ‘abc’.encode } assert\_raise(ArgumentError) { ‘abc’.encode! }

encode と encode! の引数のテストをしているようです。  
どうやら無引数の呼び出しは許可していないようなので、  
transcode.c のとこで str\_encode と str\_encode\_bang のところをいじり、  
rb\_scan\_args で引数の数をチェックするようにしたら通りました〜。

パッチを添付します。

```
   * transcode.c (str_transcode0): String#encode() with no encoding
     specified transcode the string into Encoding.default_internal.
     inspired by [ruby-core:19298].
