To compile Swiss (standard) German in LaTeX?

I want this letter

â

but cannot find in German settings:

documentclass{letter}
usepackage[utf8]{inputenc}
usepackage[T1]{fontenc}
usepackage{hyperref}
usepackage{german}{babel}
begin{document}
â 
end{document}

How can you compile correctly Swiss (standard) German language?

documentclass{letter}
usepackage[utf8]{inputenc}
usepackage[T1]{fontenc}
usepackage[nswissgerman]{babel}
usepackage{hyperref}

begin{document}

â

end{document}
