Function Details: casefold

Description

Return a casefolded copy of the string.

Extended Description

casefold is a Python string method providing aggressive Unicode case folding. More thorough than lower for international text comparison, it handles special cases like German ß to ss conversion. Works alongside upper and title in text processing workflows. While lower suffices for ASCII, casefold]@ excels in multilingual applications and locale-aware comparisons. Partners with [strip for text cleanup. Returns new string instance, keeping original intact. Essential for international text processing and case-insensitive comparisons across languages.
