I don't see why it should. I also believe parent is wrong as there are unambiguous rules about when to use ß or ss.

Never thought of it but maybe there are rules that allow to visually present the code point for ß as ss? At least (from experience as a user) there seem to be a singular "ss" codepoint.

I never said it was ambiguous, I said it depends on the unicode version and the font you are using. How is that wrong? (Seems like the capital of ß is still SS in the latest unicode but since ẞ is the preferred capital version now this should change in the future)

> How is that wrong? Not sure where, how or if it's defined as part of Unicode, but so far I assumed that for a Unicode grapheme there exists a notion of what the visual representation should look like. If Unicode still defines capital of ß as SS that's an error in Unicode due to slow adaption of the changes in the German language.

ẞ is not the preferred capital version, it is an acceptable variant (according to the Council for German Orthography).

well I don't speak german, I was asking

[birn559]

I see, wasn't clear to me on what level you were asking. The letter ß has never been generally equivalent to ss in the German language.

From a user experience perspective though it might be beneficial to pretend that "ß" == "ss" holds when parsing user input.
