DataImporter - import multiline Column

HELP !!

I'm trying to figure out the mechanism in Data Importer tool to import record Column value that is defined as "Multiline"  eg Description,

When providing quote text in CSV - with CRLF in it - fails to import with Permission type error ?? 

eg 

RoleName, Description
Role1,"This is a long Description
over 2 lines"

Shows correctly in the Data Importer setup dialogs - but errors when importing - with Permission error

Any hints / tips ? 

Tried the chr(7) , replacing vbcrlf with vbcr , vbcrlf replaced with just vblf . . . no luck 

TIA
