What does Unicode () do in Python?
Python’s string type uses the Unicode Standard for representing characters, which lets Python programs work with all these different possible characters. Unicode (https://www.unicode.org/) is a specification that aims to list every character used by human languages and give each character its own unique code.
What is Unicode in Python example?
For Python 2, strings that contain Unicode characters must start with u in front of the string. For Python 3, any string quote can begin with u , example: u”xyz” , but it has no meaning. Any string is already a Unicode datatype. The u makes the string a Unicode datatype.

How do you handle unicode errors?
The first step toward solving your Unicode problem is to stop thinking of type< ‘str’> as storing strings (that is, sequences of human-readable characters, a.k.a. text). Instead, start thinking of type< ‘str’> as a container for bytes.

How do I get the Unicode of a character in Python?

What is Unicode data type in Python?
Type ‘unicode’ is meant for working with codepoints of characters. Type ‘str’ is meant for working with encoded binary representation of characters. A ‘unicode’ object needs to be converted to ‘str’ object before Python can write the character to a file.

Decoding UTF-8 Strings in Python

Is UTF-8 and ASCII same?
For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration. Other Unicode characters are represented in UTF-8 by sequences of up to 6 bytes, though most Western European characters require only 2 bytes3.
