I am attempting to import a CE 4.1.0 .ktr into a 4.2 enterprise repository and each time I do I receive the following error message:

Unable to save repository element [/home/mcasper/j_SCHDLR_MATT]
javax.xml.bind.UnmarshalException - with linked exception: [com.ctc.wstx.excWstxUnexpectedCharException: Illegal character ((CTRL-CHAR, code2)) at [row,col {unknown-soruce}]: [1,1831]]

I am able to connect to the repository and explore successfully. I am connecting remotely to the repository from Spoon; the enterprise repository resides on a Linux machine.

If anyone has seen this before please let me know if there is something I need to check install/configuration wise that will resolve this issue.
