Combining Tilde

The tilde over n forms Spanish ñ; Portuguese ã and õ mark nasal vowels. Vietnamese uses it for the ngã tone; phonetic notation uses it for nasalized sounds.

What ̃ means

Language and base letter decide. In medieval Iberian writing, scribes used it for an omitted n. Spanish ñ grew from that shorthand; Portuguese nasal vowels use the mark over a and o.

A related Latin apex, a mark for long vowels, appears in late first- or early second-century inscriptions. Vietnamese’s ngã tone follows Greek perispomeni, a pitch mark.

Why does the combining tilde float?

Fonts position it. Type the base first. Some fonts misplace it. One visible letter may be stored whole or as a base plus this mark; unnormalized searches can miss either form.

The spacing tilde stands alone; this mark attaches to a base letter.

Why does ̃ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
