You need box drawing [1] characters.

When you need fonts with a wide range of character the Noto [2] family 
is a good choice.

%%%% begin example
\definefontfamily [noto] [rm] [Noto Serif]
\definefontfamily [noto] [ss] [Noto Sans]
\definefontfamily [noto] [tt] [Noto Sans Mono]
\definetypeface   [noto] [mm] [math] [pagella] [default]

\setupbodyfont [noto]

\starttext

\starttyping
foo
└── bar
     ├── baz
     │   └── index.html
     └── index.html
\stoptyping

\stoptext
%%%% end example
