When to use each character
Combine the viewer with our other tools to select the right invisible character for each platform.
Find layout bugs fast
Paste suspicious paragraphs and instantly locate BOM markers or zero-width spaces that break alignment.
Recommendation: Pair with the Detector tool to highlight exact positions in your content.
Compare platform behaviour
Understand which platforms block tabs, convert NBSP, or keep Hangul fillers untouched.
Recommendation: Use the compatibility notes before posting content to community-driven platforms.
Educate teammates
Share the legend and details to help support teams debug user reports about “blank” messages.
Recommendation: Export a cleaned version with the Remover tool after explaining the differences.
Viewer FAQ
Why would I inspect invisible characters?
Invisible characters help format text, dodge length limits, or obfuscate filters. Inspecting them reveals which code points appear so you can fix layout bugs or moderation issues.
How do the color highlights work?
Each category uses its own highlight tint. Zero-width placeholders appear in gray/blue, while whitespace controls use warmer accents so you can identify risky characters instantly.
Can I copy characters directly from this page?
Yes. Use the Copy button on each row or inside the details panel. The copied character stays on your clipboard so you can reuse it across tools.
