What ⪙ means
Read it in the formula’s own convention. ⪙ is a technical relation sign; the surrounding notation tells you how the author applies it.
Around 2000, Unicode and the STIX scientific-publishing effort recorded extra mathematical symbols so scientific documents and exchanged files could represent notation consistently.
Specialist mathematical notation; unusual in ordinary prose.
Use ⪙ only when the source calls for this double-line form; don't silently replace the author's glyph.

1Why 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.
