0 - 3 of 3 tags for export operator

Hi All,
Is there any way to pass ASCII value of character in TextDelimiter for TPT Export Operator? I want to export  a "TAB" delimited file. But when I'm giving tab a separator, it's taking space as delimiter. So if we can give ASCII character instead of actual character, it might produce the export file with tab as delimiter.

When exporting data to a flat file we seeing that decimals with over 18 precision are being returned as zero.  MaxDecimalDigits is set to 38 so is there something else we are doing incorrectly here?
Columns 1, 3 and 5 are being exported as zero. So the first column 2687.350 ends up in the flat file as 0.
