non-printing characters

Non-printing characters are invisible formatting symbols that help control layout in documents and emails. In Microsoft Outlook, these characters—such as spaces, tabs, and paragraph marks—are essential for troubleshooting rogue formatting like unpredictable spacing or extra line breaks. While Classic Outlook includes a built-in option to show non-printing characters, the newer version of Outlook reportedly lacks this feature, prompting users to seek workarounds. This tag covers discussions about identifying, displaying, and managing non-printing characters in Outlook and other Windows applications, with a focus on practical solutions for formatting issues.
