Unicode is a standardized character encoding that assigns a unique number (code point) to every character in most of the world's writing systems. In Python, Unicode strings are used to represent text data that may include characters from various languages and scripts. This tutorial will cover the basics of working with Unicode strings in Python, including encoding, decoding, and handling different character sets.
In Python, Unicode strings are created by prefixing a string literal with 'u' or 'U'. However, starting with Python 3, all strings are Unicode strings by default.
Encoding is the process of converting a Unicode string into a byte sequence. The encode() method is used for this purpose.
Decoding is the process of converting a byte sequence back into a Unicode string. The decode() method is used for this purpose.
UTF-8 is a variable-width character encoding that can represent every character in the Unicode character set.
UTF-16 is another variable-width character encoding widely used for Unicode.
When decoding, it's possible to encounter errors if the byte sequence is not valid for the specified encoding. You can handle these errors using the errors parameter.
Python allows using Unicode escape sequences in string literals
