Why can a right-to-left override change display order?

A bidirectional format control that can alter visual ordering. Code points: U+202E. Displayed text can differ from storage order, posing security and readability risks. No fallback is suggested. Font coverage, shaping, and application acceptance were not tested, so those results are unknown.

What was checked

Right-to-left override

A bidirectional format control that can alter visual ordering.

Displayed text can differ from storage order, posing security and readability risks.

For isolated inserted text, prefer correct directional markup or scoped bidi isolates; do not blindly delete required RTL text.

What this does not prove

No OS, font, browser, application, field policy or rendering engine was tested. Unicode validity and segmentation do not establish actual display or acceptance.
