• The detector checks Unicode code points rather than only visible glyphs.
• A normal ASCII space (U+0020) is intentionally not reported as an invisible character.
• Newlines and tabs are reported because they are control/whitespace characters, even though they are expected in normal text.
• Zero-width characters can be visually impossible to notice.
• Bidirectional formatting characters can affect the visual ordering of text.
• U+FEFF can be a BOM at the beginning of a file, but it may also appear as an invisible character inside text.
• Everything is processed locally in the browser.
