I see. I found the documents. That's an issue. That usage is incorrect. It is still valid to upper case "ß" to SS since "ẞ" is fairly new as an official German character, but the other way around is not valid.
As such the current sentence in documentation also just does not make sense.
>"Since it is already lowercase, lower() would do nothing to 'ß'"
Exactly. Why would it? It is nonsensical to change an already lowercase character with a lowercase function.
Suggest to update to:
"For example, the Unicode standard for German lower case letter 'ß' prescribes full casefolding to 'ss'. Since it is already lowercase, lower() would do nothing to 'ß'; casefold() converts it to 'ss'.
In addition to full lowercasing, this function also expands ligatures, for example, 'fi' becomes 'fi'." |
