copy paste with normal eol from any format win,*nix,win

Can we get a function that will properly format the eol - end of line - no matter the original source of text - meaning - windows, linux, mac... Point is that often copy/paste between various programs - like browser, word editors, etc... when I copy to Textastic i lost all the line breaks. Notepad++ obviously knows how to it right, but it would help if Textastic can do it also.
