Eclipse character encoding

I am using Scanner to scan a .txt document in Java. However, when I open the .txt document in Eclipse, I notice some characters are not being recognized, and they are replaced with something that looks like this:

�

These characters won't even let me scan the file as

    while(scan.hasNext)

automatically returns false (if these characters are not present, then I can scan the document just fine).

So, how do I get Eclipse to recognize these characters so I can scan? I can't manually remove them because the document is quite large. Thanks.

If non of the previous answers worked, you could solve that issue by changing your Region settings if you're using Windows 11 OS.

The file you are reading must be containing UTF-8 or some other encoding characters and when you try to print them on console then you will get some characters as �'. This is because the default console encoding is not UTF-8 in eclipse. You need to set it by going to Run Configuration -> Common -> Encoding -> Select UTF-8 from the drop down. Check below screenshot:

If you need to change the character encoding for your entire Eclipse Workspace, go to Window -> Preferences. Then under General -> Workspace, change the 'Text file encoding' to the appropriate character encoding (in this case, UTF-8).
