Thanks to Dean for alerting me to this.
Update: I've amended my original post as I mis-read the spoiler and assumed it was a Charlie-centric episode, which it is not.
On UK Show "Richard and Judy", in an interview with Carlton Cuse, writer and executive producer of Lost via sattellite, he confirmed that the Charlie problem would be resolved in episode 16 which then he later confirmed the title as "The Truth About Lying".
