Djangoのテストフレームワークで、doctestを使おうと思ったら、例外のメッセージがasciiじゃないとダメというのが判明

	In [1]: t = ValueError("テスト".decode("utf8"))
	In [2]: print t
	---------------------------------------------------------------------------
	UnicodeEncodeError                        Traceback (most recent call last)
	/home/ian/src/project/<ipython console> in <module>()
	UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2: ordinal not in range(128) </td></tr>
	In [3]: t = ValueError(u"テスト") # Unicode object'</span>s don't work either </td></tr>
	In [4]: print t
	---------------------------------------------------------------------------
	UnicodeEncodeError                        Traceback (most recent call last)
	/home/ian/src/project/<ipython console> in <module>()
	UnicodeEncodeError: '</span>ascii' codec can't encode characters in position 0-2: ordinal not in range(128)

</table></div>

とやっても、うまくうごかない。以下のUnicodeDecodeErrorがでる

======================================================================
ERROR: Doctest: app.tests

Update: moriyoshiさんにより、Python 2.6 でちゃんと動くみたい
