handling cases of control sequence being unavailable

MRI addresses this by converting the control code output to the console to win32api or by enabling VT sequence output to the console.
JRuby does not do these things.

Handle this by enabling VT sequence output to the console.
If that fails, when in legacy console, SGR code printed as a garbage.
