+    Replaces space character (' ') with a tab character ('\t')
+
+    Tested against:
+        * Microsoft SQL Server 2005, 2019
+        * MySQL 4, 5.0 and 5.5
+        * Oracle 10g
+        * PostgreSQL 8.3, 9.0
+        * SQLite 3
+
+    Notes:
+        * Useful to bypass WAFs that block %20 (URL-encoded space)
+          but allow %09 (URL-encoded tab), which is valid whitespace
+          in most SQL engines
+        * This tamper script should work against all (?) databases
