Hi Max,

this works perfectly fine with Linux "str:gsub('\r','\n')", but I can’t
make it work in Windows.

I always thought that Unix used LF (\n, if I’m not wrong) to mark a new
line, and Windows used CRLF (\r\n).

How are new lines marked in the buffer? As \r instead of \r\n or \n?

At least, Notepad (the minimal plain text editor in Windows) doesn’t
recognize newlines if I attach the buffer to the PDF document as a .txt
file.

Many thanks for your help,

Pablo
