Bidirectional Override in Dart SDK

Summary

Bidirectional Unicode text can be interpreted and compiled differently than how it appears in editors which can be exploited to get nefarious code passed a code review by appearing benign. An attacker could embed a source that is invisible to a code reviewer that modifies the behavior of a program in unexpected ways.
