Hi Julian,

How about using t= he keys in every instance?

\setupregister[index][n= =3D1,method=3D{zc,pc,zm,pm,uc},style=3DWORD]
\defineprocessor[special][s= tyle=3Ditalic]

\starttext
P\index[Plenary+periti]{Plenary Council= +{\it periti} (experts)}
B\index[Plenary+beriti]{Plenary Council+{\it be= riti} (experts)}
A\index[Plenary+aeriti]{Plenary Council+aeriti (experts= )}

S\index[animals+special]{animals+=E2=80=98special kinds=E2=80=99}=
B\index[animals+bpecial]{animals+bpecial}
A\index[animals+apecial]{a= nimals+=E2=80=98apecial=E2=80=99}
U\index[animals+upecial]{animals+=E2= =80=98upecial=E2=80=99}
T\index[animals+tpecial]{animals+tpecial}
\placeindex
\stoptext

Let me come back to the unresolved (for me) question of two situatio= ns in sub entries to a book index (register). Sub entries that have formatt= ing or sub entries that are surrounded by quote marks (straight or curly, i= t makes no difference) do not appear in the correct alphabetical order.

Two attempts on my part:

text before \index[Plenary+periti]{Plenary Council+{\it periti} (experts)} text after.

text before \index{animals+=E2=80=98special kinds=E2=80=99} text aft= er. Or alternatively, \index[animals+special]{animals+=E2=80=98special kind= s=E2=80=99}

The setup for my register is a pretty standard one. The processor is= not for the 'periti' case above but I use it for book titles.
\setupregister[index][n=3D1,m=
ethod=3D{=
zc,pc,zm,pm,u=
c},style=3DWORD]
\defineprocessor[special][sty=
le=3Ditalic]
In the periti case it is the \it command that clearly interferes wit= h correct alphabetic positioning in the sub entry list. Placing +periti in = the key does not overcome that problem.

In the =E2=80=98special kinds=E2=80=99 case it is the initial single= quote mark (=E2=80=98) that causes the problem. The item comes last in the= sub entry list. And if i include a key [special], then it comes first in t= he sub entry list. Either way, it is out of the desired sorting order.

I believe I have followed the helpful suggestions of various ones, b= ut it is always possible that I have not fully understood those suggestions= . The reality is that at the moment the issue remains unresolved for me. An= y further wisdom out there to offer me?

Julian
