My program can accept data that has newline characters of \n, \r\n or \r (eg Unix, PC or Mac styles)
What is the best way to construct a regular expression that will match whatever the encoding is?
Alternatively, I could use universal_newline support on input, but now I’m interested to see what the regex would be.
The regex I use when I want to be precise is
"\r\n?|\n".When I’m not concerned about consistency or empty lines, I use
"[\r\n]+", I imagine it makes my programs somewhere in the order of 0.2% faster.
