Escape sequence for "\t" to avoid conversion to tab in userdefined XML export

Hi,
when exporting via userdefined XML you can add your own markup to the MultiTerm tree structure (field names and content) in the corresponding text fields. How can I preserve "\t" in an expression like "C:\myTool\termbase\images\" without getting "C:\myTool   ermbase\images\" or "C:\myTool\   termbase\images\"? In the first example, MultiTerm writes a tab into the export file. In the second example, I tried to escape by using "\\t", but how can I deactivate the conversion to tab?
Many thanks in advance
