Capital ẞ in LaTeX/XeTeX/lualatex/whatever

Question

I am trying to get a ẞ in my LaTeX document. How can I do this? I already tried:

Using other fonts: dejavu and libertine
Using \MakeUppercase{ß}, which sometimes produces nothing, sometimes produces "SS"
Using {\sc ß}, which sometimes produces nothing, sometimes produces "SS"
Using XeTeX and lualatex: Just leaves out ẞ and warns about the Glyph that it could not find
Using \symbol{"1E9E}, which also produces nothing

How can I do this?

Does your font support the capital-ß? ConTeXt and LuaLaTeX print any unicode-character, if it is in the font. XeTeX should do the same. — Hanseat, Apr 14 '14 at 13:38
Just for completeness it should be added that the capital ß is not a SS anymore. In Germany at least https://en.wikipedia.org/wiki/Capital_ẞ — sheß, Jan 05 '18 at 16:54
Sorry, but from history the ß is an sz-ligature and so is the uppercase. That is, uppercase ß is more likely SZ than SS because the vocal before the SZ is a long one. Wirting uppercase ß as SS always implies that the vocal before is a short one. Thus, the pronounciation is totally different. — somebody, Sep 08 '19 at 16:40

The easiest solution, if you're sure that all the fonts you use in the document have the character U+1E9E LATIN CAPITAL LETTER SHARP S, is to say

\uccode`ß="1E9E

Otherwise, you need to provide substitutes; here's an example with Linux Libertine and Latin Modern.

\documentclass{article}
\usepackage{fontspec}
\usepackage{libertine}
\usepackage{newunicodechar}

%% simplistic solution
%\uccode`ß="1E9E

%% solution with substitutions
\newunicodechar{ß}{\ss}
\renewcommand{\SS}{\iffontchar\font"1E9E \symbol{"1E9E}\else SS\fi}

\newfontfamily{\lmr}[
  Ligatures=TeX,
  SmallCapsFont=Latin Modern Roman Caps,
]{Latin Modern Roman}


\begin{document}
\Huge
groß \MakeUppercase{groß}
\scshape Groß \MakeUppercase{Groß}

\lmr
groß \MakeUppercase{groß}
\scshape Groß \MakeUppercase{Groß}

\end{document}

Linux Libertine has it. Run it with xelatex or lualatex:

\documentclass{article}
\usepackage{fontspec}
\usepackage{libertine}
\uccode`ß="1E9E
\begin{document}
\Huge
groß \MakeUppercase{groß}
\scshape Groß \MakeUppercase{Gro\char"1E9E}

\end{document}

In Lualatex, the following works:

\documentclass{article}
\usepackage{fontspec}
\setmainfont[Mapping=tex-text]{DejaVu Sans}

DejaVu is one of the fonts that include capital-ß. According to Wikipedia, there are a few more that you might have access to. Windows 7: Times New Roman, Arial, Courier New, Tahoma, Verdana, Segoe UI, Segoe UI Light, Segoe UI Semibold. Windows 8: see Windows 7, plus Cambria, Calibri, Candara, Consolas, Constantia and Corbel Mac OS X: Geneva Free fonts: DejaVu-Paket, Linux Libertine and Linux Biolinum, Junicode If your favourite font does not include capital-ß, you can map it in from a font that has it. By the way, the DajaVu-Package is compatible with classic LaTeX too. – Hanseat Apr 14 '14 at 14:05

It's more or less everywhere now.

The expl3 language provides a function tl_upper_case:nn {language} {input}, where the language code de-alt converts ß to a großes Eszett.

\documentclass{minimal}
\usepackage{libertinus}

\ExplSyntaxOn
\newcommand\toUpper[1]{\tl_upper_case:nn{de-alt}{#1}}
\ExplSyntaxOff

\begin{document}

\toUpper{Frauenfußball}

\end{document}

In newer systems, you could instead use \text_uppercase:nn. As of 2020, the documentation says that the second argument should be “a BCP 47 string,” but in fact only de-alt works, and de-DE-1996 as specified in the RFC does not. With the newer interfaces, you would therefore write:

\text_uppercase:nn {de-alt}{\text_expand:n{#1}}

The expl3 documentation claims that you can define your own mapping with \char_set_uccode:nn, but when I tested this with

\char_set_uccode:nn {`ß} {`ẞ}

within the same TeX group as a \tl_upper_case:n or text_uppercase:n, it still mapped ß to SS.
