UTF-32

एक स्थिर-चौड़ाई वाला Unicode एन्कोडिंग जो प्रति वर्ण ठीक 4 बाइट का उपयोग करता है, जो स्थान की कीमत पर सीधे कोड पॉइंट मैपिंग प्रदान करता है।

UTF-32 is the simplest Unicode encoding: every character uses exactly 4 bytes, and the value directly corresponds to the code point. This makes random access and character counting trivial.

However, UTF-32 uses 4x the memory of ASCII text and 2x that of UTF-16 for most common characters. It's rarely used for storage or transmission but can be convenient for internal string processing.

Python 3's internal string representation uses a variable-width encoding (Latin-1, UCS-2, or UCS-4) depending on the highest code point in the string, which is why `len('😀')` correctly returns 1.
