How to decipher Russian words in a PDF file?

Question

Character encoding

Using the pdfbox-1.8.2 library for Java , I read electronic railway ticket files to get information from there.
But now a new ticket format has appeared, in which, after parsing into a text file, English words are read normally, and Russian words are obtained in the form of kryakozyabr .
I tried the methods listed here , but it didn't work.
Is it possible to decipher Russian words in such a file, or is there no textual information of Russian words in it?
