Typically, you can share text files without worrying about the underlying details of how the text is stored. However, if you share text files with people who work in other languages, download text files across the Internet, or share text files with other computer systems, you may need to choose an encoding standard when you open or save a file.
When you or someone else opens a text file in Microsoft Word or in another program — perhaps on a computer that has system software in a language that is different from the language that was used to create the file — the encoding standard helps that program determine how to represent the text so that it is readable.
What appears to you as text on the screen is actually stored as numeric values in the text file. Your computer translates the numeric values into visible characters. It does this is by using an encoding standard.
This is an important document for you who are using Windows 10 and see that your old docs make no sense. All the vowel signs are in wrong places and make your documents unreadable. I do not want to badmouth about Windows 10. But to me, it seems like an enemy and it is not at all user friendly for the people who faithfully followed windows for ever. Anyway, I could recover my old docs using help from this article and I would like to share with you all.
