Understanding the Role of Text Files

A text editor lets you edit documents that are stored in plain-text format. The American Standard Code for Information Interchange (ASCII) used to be the common form, but now files typically use Unicode formats to support additional characters. These formats store text documents that, by themselves, include no special formatting or embedded features. Text files can’t include graphics, use multiple fonts, emphasize words by italicizing them, or use other features that you probably associate with word processors (although markup tools provide a partial exception to this rule).
