In general, as they are now: since the buffers are in logical order, and 
you type the search string in the logical order as well, the search 
engine generally works the same as it does now.

The issue of whether you should find a string that looks the same, but is 
not identical in the buffer's logical-order storage has been beaten to 
death.  I think the conclusion is that it's like case-insensitive search: 
in most cases, the users want to ignore such differences, but sometimes 
they want them to be significant.

So we will need to have equivalence classes, and search and other similar 
features will need to take them into consideration.  Since the current 
search code already handles letter-case, in principle the code to do that 
is in place.
