+QNBSP: Convert space to ' '
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SQL function QNBSP(text) replaces ` ` (space) by ` `. This prevents unwanted line breaks in text.
+E.g. the title 'Prof. Dr.' should never be breaked: QNBSP('Prof. Dr.')
+
+Example::
+
+    10.sql = SELECT QNBSP(Person.title) FROM Person
