U+338A "㎊" Square Pf Unicode Character

U+338A "㎊" Square Pf is a precomposed CJK (Chinese, Japanese, and Korean) compatibility ideograph representing the unit "picofarad," a term used in electronics to denote one trillionth of a farad, which is a standard measure of capacitance. This single character was created as a square-form typographic convenience, encapsulated in a two-kanji-width space for vertical and horizontal text alignment in East Asian scripts, primarily Japanese. It belongs to the CJK Compatibility block, designed to maintain compatibility with older legacy character sets that treated such unit abbreviations as atomic glyphs, and it generally represents the same meaning as the two separate characters "p" and "F" written together.
