Tip: Verify unique strings in preprocessors

Some projects include a pre-processor step to search for a string within a variable to determine whether to change the value of a variable. Make certain that such changes uniquely identify the string to avoid unintended changes to other content.

For example, a Search and Replace pre-processor searching for lbs\r\n can cause a client named Shelbs, in the data file to be replaced unintentionally with the new code if the name is followed with a carriage return and line feed.
