text - What is a cross platform regex for removal of line breaks?

Question

I am sure this has been asked before, but I cannot find it.

Basically, assuming you are parsing a text file of unknown origin and want to replace line breaks with some other delimiter, is this the best regex, or is there another?

( )|( )|( )

Answer 1

Fletcher - this did get asked once before.

Here you go: Regular Expression to match cross platform newline characters

• Spoiler Alert!

The regex I use when I want to be precise is " ?| ".
