There is, in fact, a upper case version too, U+1E9E LATIN CAPITAL LETTER SHARP S. There is, however, asymmetrical formal case relationship between them, probably since the upper case letter was added later.

If you go to https://www.unicode.org/charts/PDF/U0080.pdf, page 4, and look at the 00DF entry it says

Also see https://codepoints.net/U+1E9E and https://www.unicode.org/charts/PDF/U1E00.pdf, page 6:

Seems that I made this confusion by suggesting to name it “Sharp S” only.

As far as I know there is no Capital Sharp S.
In the Unicode Standard that Mats sent there is no Capital Sharp S mentioned.

In the other document it is called “Small Letter Sharp S”, but in the rest of the document only “Sharp S”

Let’s hear Meikal and Michael’s opinion.

Reagrds,

In the main document nothing needs to be updated. In the appendix D.5 some instances needs to be corrected. I have in those cases added "Small" a proposed edit.

I searched through the main document. Either it is referred to as "Latin Small Letter Sharp S" (10 times, 1 time in upper case) or "Sharp S" (14 times). I cannot find any "Latin Letter Sharp S".

In appendix D.5 all three variants are used. There we should replace "Latin Letter Sharp S" with "Latin Small Letter Sharp S" to be consistent. In running text where the name is used several times it should be OK with the shorter "Sharp S".

If so, we will need to go thru the whole document and change it. Because I believe we generally used just "Latin Letter Sharp S".

But perhaps the German speakers can comment on how the Sharp S is viewed by those who actually use it.
