UTF-8 is way more popular than UTF-16 so in this article and for most of your work as they are compatible with the old original ASCII standard (one character can be represented using one byte), understanding the UTF-8 is enough. they exist so that you can more conveniently express strings that would be modified by escape sequence processing. For Python 3, the way to do this that doesn't add double backslashes and simply preserves \n, \t, etc. is: Encode String to UTF-8 in Python This [], Table of ContentsUsing Backslash (\) OperatorLine Continuation in StringLine Continuation in Number ExpressionUsing Parentheses ()Line Continuation in StringLine Continuation in Number Expression Using Backslash (\) Operator We can use \ operator for line continuation in string and number expression as follows.
