All of that should be fine...

First clue above...

... second clue.

When we build on Windows, we do not expect to see the version suffix on the function symbols (i.e., the "_u_charDirection_46" should be "_u_charDirection").

This means that the build system was unable to find the "libicuuc.lib" library in its path, and instead is building using the older symbols.

This usually happens when the WebKitSupportLibraries are not installed, or are installed in the wrong place.

Do you have a folder called "WebKitLibraries/win/lib32"?
