The reason¶

"狀態" can not be converted to Japanese SJIS.
source:trunk/test/unit/lib/redmine/export/pdf_test.rb@6013#L43

$ python
>>> s = "\xe7\x8b\x80\xe6\x85\x8b" 
>>> print s
狀態
>>> s.decode("UTF-8").encode("SJIS")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'shift_jis' codec can't encode character u'\u72c0' in position 0: illegal multibyte sequence
>>> s.decode("UTF-8").encode("BIG5")
'\xaa\xac\xbaA'
>>> s.decode("UTF-8")
u'\u72c0\u614b'
