I have an issue that has been raised at least twice in this list but as 
far as I can see it has not received an answer. Perhaps someone can help 
with the following?

I have an index entry that has unicode quote marks either side: 
‘Innovative Beings’.  I need to retain those quote marks. If I put 
\index{‘Innovative’} then ‘Innovative’ is sorted under ‘ instead of 
under the letter I. How do I get my indexing to ignore the quote marks, 
at the very least the initial one?

My index setup at the moment is as follows:

\defineregister[index][compress=yes]

\setupregister[index][n=1]

\defineprocessor[special][style=italic]

The only hint I could gain from the wiki was that it might depend on 
using a method key in \setupregister, but I could not see which to use. 
Tried a few and got weird results.
