Rubooks can open OC/PDF/XLS, FB2, including support to zip-archived files.
I has localization support for Russian, German, Chinese, English and Japanese.
With rubooks you can search Texts, scrool with the volucom buttons, has support for table of contents, book cover and you can virtually open any book file anywhere on your device.
