BTEQ .SET RECORDMODE ON; in Unix creating illegible characters.

I am trying to export an SQL query from a table - this is in a standard query format i.e.
INSERT INTO DATABASE_A.TABLE_B
SELECT
COUNT(*)
FROM DATABASE_A.TABLE_A
WHERE TABLE_A.REF_1 = 0;
I then use bteq to export it in to a file so I can execute queries in order. I want to preserve the format of the query (as it can contain comments) however on export - the file is presented with: 
^D▒^D▒INSERT INTO DATABASE_A.TABLE_B
The code I am using to export is:

bteq <<-EOF

.LOGON ${LOGON};

DATABASE DATABASE_A;

.WIDTH 65531

.EXPORT DATA FILE=rw_test_sql.dat

.SET RECORDMODE ON;

.RETLIMIT 2147483407,2048;

        .SET SEPARATOR 0;

        .SET NULL AS '';

.SET SESSION CHARSET 'UTF8';

.set titledashes off;

SELECT

REQUEST_TEXT

FROM DATABASE_A.TABLE_A;

.IF ERRORCODE <> 0 THEN .QUIT 8

.EXPORT RESET

.QUIT 0

EOF

 
I am using Solaris 10 on KSH. so my question to you is do you know what the cause of this is and how to resolve it?
.SET RECORDMODE OFF; does solve it however the SQL comes in its unformatted text causing it to fail with comments.
