how to match any character with ruby regexp?

[Nanyang Zhan]

It seems work well, but I'm not confident that the (.)* will safelly
match all the characters inside a <a> tag, for example, what if there is
a new line?
So, for ruby regex, which symbol can be surely used to represent any
character of a string? Thanks.

irb(main):004:0> "a\nb".match(/.+/).to_a
=> ["a"]
irb(main):005:0> "a\nb".match(/.+/m).to_a
=> ["a\nb"]

A dot.

=> ["a\nb"]
