The effect uses Unicode combining marks; alignment can vary between fonts.

How Unicode strikethrough works

The standard strike inserts U+0336 COMBINING LONG STROKE OVERLAY after each visible character. Underline uses U+0332 and diagonal variants use other combining overlays.

Why rendering varies

Combining marks are positioned by the destination font and text engine, so line height and continuity can differ between apps.
