Validate what??

Apr 14, 2014 at 8:23 PM
I can't understand this "Validate" what is for.
Does it modify the txt file? If the file is in the list with some "ASCII" or "UTF-8" encoding doesn't mean the file is already valid?
Why should I validate???
:-)
please provide just a minimum documentation about this, the only obscure feature of this File Encoding Checker.
thank you!
