U+1F5DA Increase Font Size Symbol

U+1F5DA was added in Unicode version 7.0 in 2014. It belongs to the block U+1F300 to U+1F5FF Miscellaneous Symbols and Pictographs in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+1F5DA forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

In metal typesetting, a font or fount is a particular size, weight and style of a typeface, defined as the set of fonts that share an overall design. For instance, the typeface Bauer Bodoni (shown in the figure) includes fonts "Roman" (or "regular"), "bold" and "italic"; each of these exists in a variety of sizes.
In the digital description of fonts (computer fonts), the terms "font" and "typeface" are often used interchangeably. For example, when used in computers, each style is stored in a separate digital font file.
In both traditional typesetting and computing, the word "font" refers to the delivery mechanism of the typeface. In traditional typesetting, the font would be made from metal or wood type: to compose a page may require multiple fonts or even multiple typefaces.
