U+1D7D8 Mathematical Double-Struck Digit Zero

U+1D7D8 was added in Unicode version 3.1 in 2001. It belongs to the block U+1D400 para U+1D7FF Mathematical Alphanumeric Symbols in the U+10000 para U+1FFFF Supplementary Multilingual Plane.

This character is a Decimal Number and is commonly used, that is, in no specific script. The codepoint has the decimal value 0.

The glyph is a font version of the glyph Glifo para U+0030 Digit Zero. It has no designated width in East Asian texts. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. This number joins with other adjacent letters and numbers to form a word. U+1D7D8 forms a number with similar characters, which prevents a line break inside it. The glyph can be confused with one other glyph.

El Wikipedia tiene la siguiente información acerca de este punto de código:

0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 has the result 0, and consequently, division by zero has no meaning in arithmetic.

As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, "205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya.

Common names for the number 0 in English include zero, nought, naught (), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (). Informal or slang terms for 0 include zilch and zip. Historically, ought, aught (), and cipher have also been used.
