1.133 nicm 34: * https://vt100.net/emu/dec_ansi_parser
1.28 nicm 35: *
36: * With the following changes:
37: *
38: * - 7-bit only.
39: *
40: * - Support for UTF-8.
41: *
42: * - OSC (but not APC) may be terminated by \007 as well as ST.
43: *
44: * - A state for APC similar to OSC. Some terminals appear to use this to set
45: * the title.
46: *
47: * - A state for the screen \033k...\033\\ sequence to rename a window. This is
48: * pretty stupid but not supporting it is more trouble than it is worth.
1.37 nicm 49: *
50: * - Special handling for ESC inside a DCS to allow arbitrary byte sequences to
1.77 nicm 51: * be passed to the underlying terminals.
