In CEA-708 we have subtitle color for each row (subtitle line)
Often the color disappears from the expected line. We get all the colors in function SetPenColor in fg_color (as far I tested) but often it is assigned to the wrong row number of window, percentage of confusion depends on example video. It's necessary to correct the confusion.

Result:

38
00:02:37,307 --> 00:02:38,608
<font color="aaaaaa">When you've been making         </font>
delicious natural cheese

Expected:

38
00:02:37,307 --> 00:02:38,608
<font color="aaaaaa">When you've been making         </font>
<font color="aaaaaa">delicious natural cheese        </font>

^ In this example all the colors is equals to 42 (fg_color == 42), but there are blank lines anyway.

@cfsmp3 After reading the documentation and code I think I found a mistake. Pen colors and attributions are independent from line number, but in current master we storing it for the whole lines. There are the real fg_color changing in SetPenColor (wrote small subprogram): korean.txt (yellow color for first line as in 708 player), usa.txt, histw.txt - almost all text is gray.
Same thing with SetPenAttributes - we can have italicised only one word in the line, but have either full italicised line or full not italicised
I have to rewrite code architecture - single pen for single window as it is written in the documentation
