No more detail for the moment. Here is the exception:

Start by reading ModelsLibraryIndexReader.scala around readInfoMap at lines 15–16, then trace the model-index loading path through BufferedSource and the reported Java runtime. Reproduce the failure with the stated Windows 7 and Java 6 environment if available; done means Asian-user model indexes load without UnmappableCharacterException.
