Non-printing characters or formatting marks are characters for content designing, which are not displayed at printing. They have a function to format the content when printing it or showing it on a screen. A few examples are a tab or new line ‘command’.
When a source file or system contains such non-printing characters, use the following values to find them and replace them or us them for the Split Field transformation.
[:space:]
[:tab:]
[:newline:]
[:return:]
All values are lower cased.
