U+FE12 "︒" Presentation Form for Vertical Ideographic Full Stop Unicode Character

U+FE12 "︒" Presentation Form for Vertical Ideographic Full Stop is a compatibility variant of the standard Chinese and Japanese full stop, specifically designed for use in vertical writing systems. When text is laid out in vertical columns rather than horizontal lines, this character rotates the usual full stop to maintain proper orientation and alignment, appearing as a small, centered dot instead of a corner mark. It is part of the CJK Compatibility Forms block, bridging the stylistic needs of traditional East Asian typography while remaining functionally identical to its horizontal counterpart, U+3002.
