TypeError: string indices must be integers

Getting this error, when querying a layout;

It seems to be related to a issue reported here; gozoinks/pyfilemaker#3

I seem to be able to fix it by having a fail safe for unicode;

Don't know what that might entail for the rest of the code, but I can do a PR.
