New nb implementation of 42638 and related issues resulted in infrastructure for
providing a per project endoding property.

Now 97848 is an umbrella issue for the actual per-project type  implementation
of it, which has refs to
issues filed so far for some other project types - from comments in that issue

-The guidelines for project types about this is:

Every project type should provide the FileEncodingQueryImplementation. There is
already an issue for j2ee project (enterprise).  If you know about some other
project type not covered
by dependent issues create a task for it.  Or if a module might use or
manipulate sense of encoding like introduce a DataObject, it could need to
provide this implementation.

Can you see if anything in identity would need this ?
Tomas Zezula is developer who knows about this kind of implementation

I realize identity is not a project type but
