+** Use field trimming if:
+- The leading or trailing white space is not needed for the business process.
+- The input fields have uniquely identifying business objects.
+- The input fields have a fixed field length.
+** Do not use field trimming if:
+- The use case explicitly requires leading/trailing white space. For example,
+  for formatted text such as chats, comments, descriptions, source code, or for
+  file names (according to the supported OS behavior).
+- For text areas where users would expect leading white space as a formatting
+  tool.
