       0       reset all attributes to their defaults
       1       set bold
       2       set half-bright (simulated with color on a color display)
       4       set  underscore (simulated with color on a color display)
               (the colors used to simulate dim  or  underline  are  set
               using ESC ] ...)
       5       set blink
       7       set reverse video
       10      reset  selected mapping, display control flag, and toggle
               meta flag (ECMA-48 says "primary font").
       11      select null mapping, set display control flag, reset tog‐
               gle meta flag (ECMA-48 says "first alternate font").
       12      select null mapping, set display control flag, set toggle
               meta flag (ECMA-48 says "second  alternate  font").   The
               toggle meta flag causes the high bit of a byte to be tog‐
               gled before the mapping table translation is done.
       21      set normal intensity (ECMA-48 says "doubly underlined")
