Force Encoding Error

[nickbender]

Running into an issue when running bulk updates on existing data.

Whenever a trigram create is attempted on a field with a nil value, I receive the following bomb:

** Execute environment
** Execute fuzzily:bulk_update
Running Router#bulk_update_fuzzy_name
Running Router#bulk_update_fuzzy_dns_name
rake aborted!
undefined method `force_encoding' for nil:Fuzzily::String

Do all indexed fields have to have a value? If so, is there a way to override or skip this behavior?
