Add Unicode support to client interface

[billschereriii]

Description

This enables users from all around the world to work in their native language/character set.

Justification

Users from non-English speaking countries will gain access to full character sets

Implementation Strategy

Easiest approach is to add parallel routines to the interface for Unicode support, then push the plumbing all the way through. Making sure that strings are tracked by type will be a good safety feature.
