What ᷼ means
In Uralic transcription, it divides two-vowel sequences at the syllable boundary.
An early example of the UPA double inverted breve appears in a 1908 Finnish publication of the Kalevala, a Finnish epic. That places the mark in a Uralic Phonetic Alphabet tradition older than Unicode.
The Unicode proposal uses ͡ for a diphthong in its Uralic example. The International Phonetic Alphabet (IPA) uses ͡ and ͜ as tie bars that join two sound symbols into one unit. The arch shape alone does not tell you which convention is meant.
Why does ᷼ look detached?
It needs a font that can place one mark across two letters.
A font with bridging-diacritic support centers the mark over the gap. If the neighboring letters have very different widths, it can still look off-center; that is a rendering issue, not a change in reading.
Place ᷼ between the two base letters; putting it after the pair will not bridge them.
A specialist mark in Uralic phonetic transcription; its position marks a vowel boundary between syllables.
Do not substitute an IPA tie bar: it joins phonetic symbols into one unit, while ᷼ marks a syllable boundary in UPA.

1Does ᷼ need font support?
Yes. It needs a font that positions bridging diacritics across both letters; unequal widths may leave it off-center.
