DCS parsing is optional because fish temporarily switches to the alternate screen before printing any DCS commands.
|
||||
However, since GNU screen neither allows turning on the alternate screen buffer by default,
|
||||
nor treats DCS commands in a compatible way,

||||
fish's initial prompt may be garbled by a DCS payload like ``+q696e646e``.
