Functions containing Unicode characters break nativization on Clang-hosted target platforms.

The UHT boilerplate code that's generated from a converted Blueprint class header file generated from a Blueprint class containing one or more function names with non-ASCII characters will fail to compile properly on a Clang-hosted platform (e.g. Linux) due to being improperly encoded as UTF-16.

1. Open the attached project in the UE4 editor.
2. Attempt to package it for Linux or some other Clang-hosted platform.
3. A compile error will result:

   error: UTF-16 (LE) byte order mark detected in 'NewBlueprint__pf1010915279.gen.cpp', but encoding is not supported
