Regular Expression that would include control characters

I have a Java process that uses different regular expressions based on which file type I'm processing. It determines whether the record being read should be kept or not.

I have one file type that I want to include everything. So, I created its regular expression to:

.*

This normally works, but I just ran into a problem where a record contained an embedded line separator (\u2028) character which cased the regex match to fail (resulting in the record not being kept).

Can anyone recommend a regex pattern that would accept any and all characters?

Use `(?s).*`.... – Wiktor Stribiżew Jun 15 '17 at 20:37
Use `[^]*`... ? – Patrick Roberts Jun 15 '17 at 20:39

@PatrickRoberts That causes `PatternSyntaxException: Unclosed character class near index 3` – Andreas Jun 15 '17 at 21:06
@Andreas oh, I wasn't sure if it would work, it was just a guess. I'm used to JavaScript flavor of regexes. – Patrick Roberts Jun 15 '17 at 21:10
Wiktor's suggestion worked. Thanks! – Todd Jun 15 '17 at 21:12
