PDF Output Broken When Using Official Chinese Translation

[sprankhub]

When using the official Chinese translation, the output of the PDF is broken. See this screenshot (thanks @ming2014):

When developer mode is enabled, you get a notice like this:

This problem also occurs when using the default Magento PDF engine. Hence, it is a Magento bug and not a FireGento_Pdf bug. Anyway, we should think of providing a solution for it.
