here is the example pdf file
50006377.pdf
through Pages -> Texts -> R -> T i can get from the box with chinese characters is "%E9%9B%84%2C%E5%AF%8C%E7%94%B0". after decoding i get "雄,富田". which is aber not fully word. it does not show the first word. it should be "朝雄,富田". it means what i get the original code lost "%E6%9C%9D".
in the pdf it shows correctly.
could you show me how should show the full word. thanks.
