Generate a short blank-looking WhatsApp message sample, copy it, and test it before sending. The tool shows the Unicode character used so you can compare what WhatsApp keeps or removes.
Hangul Filler is usually the best first test for a blank-looking message because it has presence while often appearing empty. Zero Width Space is useful for no-width tests, and No-Break Space helps check spacing behavior.
WhatsApp support may vary by phone, app version, web client, and chat field. Some versions may trim invisible-only messages or display the character differently.
Use blank-looking messages for formatting and compatibility tests. Avoid spam, flooding, harassment, evasion, impersonation, or misleading behavior.
