I've been translating a few text files recently for quiz answers and other reasons and I thought I would share how I've been doing it.
First you need
Notepad++Then you are going to want to right click the text file and right click Edit with Notepad++.
After that you are going to want to click the Encoding tab and find Japanese under the Character Sets part.
From there you can just copy the Japanese text into Google Translate or any other translate program you might know.
