This file is really not new. It has been discussed multiple times. The short answer is that, this was included when Xojo added Unicode support.

> With the new version 2014r3, there are three new dll in the exe Lib folder: icudt53.dll, icuin53.dll and icuuc53.dll. The first of these dlls is 20 Mb big. What are these dlls for? I see no new big feature for Windows in this new release. Every time the exe file is bigger and bigger and it’s difficult for us to understand why.
