SQLTable() does not like escape sequences in catalog name parameter

My application uses the IBM Informix ODBC driver.
Issue with respect to ODBC call SQLTables.
As per ODBC specifications for SQLTables, the catalogname can have escape sequences ('\').
Say I have a database: db_en.

In my call to SQLTables,
char dbname[10] = "db\\_en" ;
SQLTables (hTableStmt, (SQLCHAR*)dbname, SQL_NTS, (SQLCHAR *) "sanav", SQL_NTS, (SQLCHAR *)"rep\\_mytable" , SQL_NTS, (SQLCHAR *) "TABLE", 5);

The get the below error,
ERROR: -202: HY000 : [Informix][Informix ODBC Driver][Informix]An illegal character has been found in the statement.

Now if I change the catalog name without underscore, say
char dbname[10] = "mydb" ; , it works fine.

From my analysis I find that there are no issues if tablenames have escape sequence('\'). The problem exists only for catalog names.
This seems broken and is not as per ODBC specs.

I suspect it is a driver issue.

My environment:
OS: Linux 64 bit
IDS: 12.10
IBM Informix CSDK Version 4.10
