JDBC FastLoadCSV Connection; multi character field separator??

Is this possible? I see in the FastLoadCSV docs that you can specify other field separators besides comma.
I'm using the old CLI version of fastload all the time now, and a lot of my data has unfiltered user input, so one of my favorite features is to be able to use something like |~| or ^^^  as a field separator. If I can't do this via JDBC, I'll have to change a lot of my load processes, and watch out for users that put ascii pictures in their description fields.
