D83

D83 is an alphanumeric designation used in several unrelated areas, including computing, transportation, and product coding. It has no universally fixed meaning and should be interpreted from its context.

In Unicode and UTF-16 encoding, D83 is seen as part of the high-surrogate range. High surrogates range from D800 to DBFF; many non-BMP characters are encoded as a pair of code units. The string D83D DE00 is the surrogate pair for U+1F600, the grinning face emoji, illustrating how D83D begins a typical surrogate pair. Therefore, D83 appears as a leading fragment in some Unicode representations but by itself does not denote a character.

In French road numbering, D83 may refer to a departmental road with designation "D" followed by a number, managed by a department. Such roads connect towns and local facilities and vary by department; the exact route and status depend on the issuing department.

In other contexts, D83 may be used as a model or catalog number, product code, or internal identifier. Without context, its meaning is ambiguous.
