title: Why is there an escape sequence for VERTICAL TAB?
body: <p>Another question, <a href="https://stackoverflow.com/questions/3380538/what-is-a-vertical-tab">What is a vertical tab?</a>, describes what the vertical tab character was originally used for.</p>
  
  <p>But why was <code>U+000B VERTICAL TAB</code> considered important enough to be allocated an escape sequence (<code>'\v'</code>) in the first place, in C and many other programming languages?</p>
