Answer 1

Check here for the lists of Java supported encodings

Most common single-byte encoding that includes non-ascii characters is ISO8859_1; maybe your file is that, and you should specifiy that encoding for your FileInputStream

Answer 2

The problem might not be with the file but with the console where you are trying to print. I suggest you follow the following steps

1. Make sure the file you are reading is encoded in UTF-8.
2. Make sure the console you are printing to has the proper encoding/charset to display these characters

Finally, this article Unicode - How to get characters right? is a must read.
