Necessary information

• Is this a regression (i.e. did it work before)? NO
• What platform did you use? LINUX
• What were the used arguments? Doesn't matter in this case

Additional information

I was going through the codebase and testing things I observed a function get_write_interval where this function returns the bounds in which captions are present. So that means if caption/dtvcc_symbol in that case is default or 0 then it should return (0,0) answer But it is returning (0,209) even the whole row is empty

Reason behind it: 0x00.is_set() is also considered as true

Question: Is this a intentional behavior or just a mistake which is never noticed?
