Edit filter settings
An example from Microsoft Office support: in the Cyrillic (Windows) encoding, the character Й has the numeric value 201. When you open a file that contains this character on a computer that uses the Cyrillic (Windows) encoding, the computer reads the 201 numeric value and displays Й on the screen.
However, if you open the same file on a computer that uses a different encoding, the computer displays whatever character corresponds to the 201 numeric value in the encoding standard that the computer uses by default.
This check box becomes active when you select Text – Choose Encoding (.txt) from the File type drop-down menu. When you put a check in the box and press the Save button, a ASCII Filter Options dialog opens.
The dialog allows you to pick which standard you use to translate numeric values into corresponding characters. A text file actually stores characters as numeric values, which needs to be translated.
Computers are set up for the regions of the world they operate in. Therefore ASCII standards are different from region to region. Opening a file that is encoded with one standard on a computer that is set with a different standard will most likely cause characters in the document to be rendered wrong.
Saving a document as Text – Choose Encoding and then setting the filters is important when you are sharing a document with people who are in different parts of the world. LibreOffice is also a great tool for creating documents with multiple languages.
Here are the options in the ASCII Filter Options dialog.There is a Character set drop-down menu and three radio buttons for the Paragraph break section.
There are 78 choices in the Character set list.
Paragraph break defines the type of break for a line of text. 
CR and LF creates a Carriage Return and a Line Feed. CR is for carriage return. LF is for Line Feed.
Choose the desired standard set from the drop-down menu.
Choose one of the three radio buttons. Finally click the OK button. This will save the document in the chosen set.
