Received bubble layout tester

This page helps test how a received-message or neutral grey-bubble style field handles empty-looking Unicode. It only creates text; it does not control received-message styling, sender identity, or app bubble color.
Use this page for grey or received-side bubble rendering checks. It is separate from the blue bubble page because many apps style outgoing and incoming messages differently, and the same Unicode can render differently in each context.
Hangul Filler is the best first test when a bubble needs a blank-looking character with presence. No-Break Space is better for spacing width. Zero Width Space is useful for no-width checks but is often removed.
Grey bubble rendering can change by app, theme, operating system, sender/receiver state, and device. Some apps remove invisible-only text or require a visible message body.
Use this for rendering and compatibility checks only. Do not use empty grey bubble samples for fake conversations, harassment, evasion, or misleading screenshots.
