If you make the internal default for the repository be the native
platform encoding and the workspace encoding in the absence of specific
rules also be the platform encoding, you will cover a substantial part
of the total user base without needing specific rules.

One possibility for existing repositories containing files with
non-native encoding would be that they continue to be stored in the
repository with their existing line end encoding and that they be
transferred to/from the user workspace with the repository encoding. If
the user overrides the current encoding then the new encoding should be
used when the file is returned to the repository. It might be nice to
provide a command for those users who choose to migrate to standard
settings to perform the conversion in a single step. Documentation
should then point out the possible consequences of such migration.
