[Java] InputStreamReader

An InputStream is a binary stream, so there is no encoding. 
When you create the Reader, you need to know what character encoding to use, and that would depend on what the program you called produces (Java will not convert it in any way).


If you do not specify anything for InputStreamReader, it will use the platform default encoding, which may not be appropriate. There is another constructor that allows you to specify the encoding.


If you know what encoding to use (and you really have to know):

new InputStreamReader(process.getInputStream(), "UTF-8") // for example
