  • Creating UTF-8 files in Java from a runnable Jar

    - by RuntimeError
    I have a little Java project where I've set the properties of the class files to UTF-8 (I use a lot of foreign characters not found on the default CP1252). The goal is to create a text file (in Windows) containing a list of items. When running the class files from Eclipse itself (hitting Ctrl+F11) it creates the file flawlessly and opening it in

    I've been working on a little project involving Steam Condenser, a Steam API written in Java, but I haven't been able to actually do anything with it. I'll explain.
