Invisible Character Viewer

Invisible Character Viewer is a straightforward web tool that reveals the hidden characters lurking in your text. You paste your text into its interface, and it automatically scans for and highlights any non-printing Unicode characters. This includes everything from common tabs and line breaks to more obscure zero-width spaces and directional formatting marks. The tool makes these invisible elements visible, showing you exactly where they are and what they are, which is the first step to understanding why a piece of text might be behaving strangely.

What sets Invisible Character Viewer apart is its depth and clarity. It doesn't just point out a problem; it educates you about it. Hovering over a highlighted character reveals its precise Unicode code point and official name. The site also features a comprehensive legend that details over 50 different invisible characters, from the Null character to the Mongolian Vowel Separator, complete with links to more information. For immediate cleanup, a single button click can strip all these hidden characters from your text, which is invaluable for sanitizing inputs.

This tool is most beneficial for developers and QA professionals who need to debug text-related bugs, or for anyone who has ever been puzzled by text that looks empty but isn't. A common real-world use is cleaning text copied from a Large Language Model (LLM) like ChatGPT, which sometimes inserts hidden formatting characters. It's also practical for content moderators checking for users attempting to bypass filters with invisible characters in usernames or comments. It's a simple, focused utility that solves a specific but surprisingly frequent problem.
