AFAIK, positions 128-159 were originally reserved for control codes.
For example, VT100-class terminals will interpret CSI (code 145, I think)
identically to '<ESC>[' (a very common prefix in VT100 escape sequences),
which, I imagine, was to reduce terminal traffic for escape-sequence
intensive apps (like curses-based apps and full-screen editors).
