U+000B "VT" LINE TABULATION Unicode Character

U+000B "VT" LINE TABULATION is a control character from the C0 control code set, historically known as a vertical tab. It was used in older computing and printing systems to move the cursor or print head vertically down a fixed number of lines, typically without advancing horizontally, serving as a form of vertical spacing distinct from a line feed or form feed. While largely obsolete in modern text processing and plain text files, it remains defined in Unicode for compatibility with legacy data and protocols, and its behavior can still be recognized by terminal emulators or specialized software that interpret raw control codes.
