Start in lib/python2.7/site-packages/site-packages/wdb/ui.py at do_eval, line 498, where the traceback shows the failure. Reproduce the reported UnicodeDecodeError through the evaluation flow and inspect the values combined at that point. Done when the reported path handles the shown non-ASCII input without raising the decoding error.
