A FieldIndex does support Unicode values.
However, *all* indexed values must then be either pure ASCII or unicode!

Look at the traceback. Always do this when you get errors!

Almost surely, your index contains a non ASCII and non unicode value.
When the index lookup compares the keys, the non ASCII value
is converted into unicode (as there is another unicode operand)
and this fails.

You can use a "Managable FieldIndex". It allows you to convert
all values to unicode with your chosen encoding (specifying the
encoding could be easier -- maybe in the next release).
