Combining Double Circumflex Above

It marks vowel sequences; the reading depends on the spelling tradition. Jens Christian Svabo used it in an older spelling of Faroese, the language of the Faroe Islands, to mark two diphthongs: pairs of vowel sounds that glide together in one syllable. Some Old English editions use it to show that a diphthong should be read in two syllables. Its sound depends on the convention in the edition.

Svabo’s first Faroese dictionary manuscript, completed in 1773, gives a dated example. His spelling followed pronunciation, while modern standard Faroese spelling follows word history more closely.

How do I type ᷍ between two letters?

Place ᷍ after the pair’s first letter. In e᷍a, the mark follows e in the stored text, though it is meant to extend over both letters. Some fonts cannot position a combining mark across two letters correctly, leaving it floating or detached.

The double tilde shares its two-letter convention

The combining double tilde ͠ follows the same pattern: it sits after one letter in stored text and is intended to extend across two. That shared structure makes it a related mark.
