If you are non-English speaking country native, and you are testing your application for your locale then you may face difficulty in testing your application through eclipse console. By default, Eclipse converts non-English characters as question marks (?) or some weird characters because by default eclipse’s console encoding is Cp1252 or ASCII, which is unable to display other non-English words.
You can easily change the default encoding to UTF-8 i.e. Unicode by setting below option.
Now when you use any non-English character in IDE and even print in console, it works perfect.
Here If you do not add Unicode support then above program will look like this.
Drop me comments if something is not clear.
Happy Learning !!
