U+51E7 CJK Unified Ideo­graph-​51E7

U+51E7 was added in Unicode version 1.1 in 1993. It belongs to the block U+4E00 to U+9FFF CJK Unified Ideographs in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Letter and is mainly used in the Han script. The Unihan Database defines it as kite. Its Pīnyīn pronunciation is zhēng.

The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. U+51E7 offers a line break opportunity at its position, except in some numeric contexts.

The Wikipedia has the following information about this codepoint:

A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs do not need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from the kite, the hovering bird of prey.

The lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the lines or tethers to which the kite is attached. The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat, free-falling anchors as in paragliders and fugitive parakites or vehicle).

The same principles of fluid flow apply in liquids, so kites can be used in underwater currents. Paravanes and otter boards operate underwater on an analogous principle.

Man-lifting kites were made for reconnaissance, entertainment and during development of the first practical aircraft, the biplane.

Kites have a long and varied history and many different types are flown individually and at festivals worldwide. Kites may be flown for recreation, art or other practical uses. Sport kites can be flown in aerial ballet, sometimes as part of a competition. Power kites are multi-line steerable kites designed to generate large forces which can be used to power activities such as kite surfing, kite landboarding, kite buggying and snow kiting.
