 Hm... i do not think it is wrong, but:
 1) MKVToolNix - extract .srt subtitles with CRLF (at least in windows
 release)
 2) Windows OS use CRLF newline style
 [https://en.wikipedia.org/wiki/Newline#Representation] (Atari TOS,
 Microsoft Windows, DOS (MS-DOS, PC DOS, etc.), DEC TOPS-10, RT-11, CP/M,
 MP/M, OS/2, Symbian OS, Palm OS, Amstrad CPC, and most other early non-
 Unix and non-IBM operating systems)
 3) Aegisub - create.srt subtitles with CRLF (at least in windows release)

 Maybe, but it can use only two options -eol CRLF - for Win or -eol LF -
 for Unix :)
 It is difficult question :)

 Hm... notepad.exe :D - it read it, but without new lines.

 Maybe, same DOS and Symbian DVD players falls :D

 Also, .srt have CRLF - but in strange places (Why does it not have CRLF in
 all .srt file?):
 I marked it green:
