Private Use High Surrogate-Dbf6

Private Use High Surrogate-Dbf6 at U+DBF6 is a UTF-16 high-surrogate code point, meaning it is an encoding component rather than a standalone written symbol. It sits in the High Private Use Surrogates block and is reserved for forming surrogate pairs that can address supplementary private-use characters. In practice, U+DBF6 may appear inside software that stores text as UTF-16 when representing a character from the Supplementary Private Use Area. It would be followed by a low surrogate code unit; only the pair together identifies a private-use character whose meaning is defined by a font, application, organization, or closed data system. People most often see this value while debugging malformed text, inspecting strings from Windows, JavaScript, Java, .NET, or databases, or diagnosing why a proprietary icon, corporate glyph, or custom symbol failed to survive interchange. The main pitfall is that U+DBF6 by itself is ill-formed Unicode text: many systems replace it, reject it, or lose the intended private-use character if the matching low surrogate is missing or separated.
