Non-printable characters in a results cell are not escaped. Eg- \b is displayed as what appears to be an empty string.

Two possible solutions that I can think of right now:

1. add a quote to all strings that either start or end with a non-printable character
2. preprocess all result strings and convert a subset of non-printable chars to their unicode number (ie- \uXXXX). We probably only want to do this for a fixed set of chars, probably the ascii chars that are known to be control characters.
