Function Details: casefold

Description

Return a casefolded copy of the string.

Extended Description

The casefold() method returns a casefolded copy of the string, which is a more aggressive form of lowercasing. It's primarily used for caseless matching. Casefolding is similar to lowercasing but more thorough, as it's designed to remove all case distinctions in a string. For most use cases, lowercase() is sufficient, but casefold() can be useful when dealing with certain Unicode characters.
