U+3387 was added to Unicode in version 1.1 (1993). It belongs to the block CJK Compatibility in the Basic Multilingual Plane.

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

The glyph is a Square composition of the glyphs G B. It has a Wide East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. In text U+3387 behaves as Ideographic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

The gigabyte (/ˈɡɪɡəbaɪt/ GIG-ə-byt or /ˈdʒɪɡəbaɪt/) is a multiple of the unit byte for digital information.

The prefix giga means 109 in the International System of Units (SI), therefore one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB.

This definition is used in all contexts of science, engineering, business, and many areas of computing. However, historically, the term is also used in some fields of computer science and information technology to denote 1073741824 (10243 or 230) bytes.

The term "gigabyte" is thus ambiguous today. For semiconductor RAM, the "gigabyte" denotes 1073741824bytes. For hard drive capacities as described and marketed by the drive manufacturers, the gigabyte denotes 1000000000bytes, but when a 500-GB drive's capacity is displayed by, for example, Microsoft Windows, it will be reported as "466 GB", where "GB" then means 1073741824bytes.

To address this ambiguity, a set of unique "binary prefixes" has been standardized in the International System of Quantities, each binary prefix denoting an integer powers of 1024. According to these, "gigabyte" or "GB" would always refer to 1000000000bytes, and what is now labeled as a "1 GB" RAM module would be described as "1 GiB" or "one gibibyte". However, these have seen only limited usage in product labeling and software.
