U+3385 "㎅" Square Kb Unicode Character
U+3385 "㎅" Square Kb is a precomposed typographic symbol representing the unit "kilobit" or "kilobyte" (abbreviated as Kb), designed for compatibility with East Asian text encodings where such units are often displayed in a single square character space. This character is part of the CJK Compatibility block, which includes various squared Latin abbreviations used in Japanese, Chinese, and Korean writing systems to maintain uniform character widths in grid-based layouts. It is distinct from the standard Latin letters "K" and "b" because it is intended for use in specialized contexts like technical documentation or data storage references, where the squared form helps visually integrate the abbreviation into monospaced or ideographic text environments.
