If you see hollow rectangles instead of characters or if characters are missing entirely then you are not using the correct font. You need to use a font that can display the characters in your file. If you’ve received a text file from another person, or opened a file created on another computer, it may not immediately be readable in EditPad. Unicode is a standard that aims to encompass all traditional character mappings, and all scripts used by current and historical human languages. You can’t mix Chinese, Russian and French in a text file, unless you use Unicode. In addition to conversion problems, the main problem with using traditional character mappings is that it is impossible to create text files written in multiple languages using multiple scripts.
#TEXT EDITOR UNICODE FOR MAC HOW TO#
Since different computer manufacturers had different ideas about how to create character mappings, there’s a wide variety of legacy character mappings.
As a result, different character mappings are used for different languages and scripts. This means that only 256 distinct characters can be represented in any text file. Traditional character mappings or code pages use only 8 bits per character. When saving a file in one application, and opening that file in another application, both applications need to use the same character mappings. When you open a text file, the numbers are read and mapped back to characters. When you save a text file, each character is mapped to a number, and the numbers are stored on disk.
