I know it seems a bit redundant but I'd like a regex to match anything.
At the moment we are using ^*$ but it doesn't seem to match no matter what the text.
I do a manual check for no text but the test view we use is always validated with a regex. However, sometimes we need it to validate anything using a regex. i.e. it doesn't matter what is in the text field, it can be anything.
I don't actually produce the regex and I'm a complete beginner with them.

Matching a Single Character Using Regex ' dot character in a regular expression matches a single character without regard to what character it is. The matched character can be an alphabet, a number or, any special character.
The fundamental building blocks of a regex are patterns that match a single character. Most characters, including all letters ( a-z and A-Z ) and digits ( 0-9 ), match itself. For example, the regex x matches substring "x" ; z matches "z" ; and 9 matches "9" .
Short for regular expression, a regex is a string of text that lets you create patterns that help match, locate, and manage text.
(. *?) matches any character ( . ) any number of times ( * ), as few times as possible to make the regex match ( ? ). You'll get a match on any string, but you'll only capture a blank string because of the question mark.
The regex .* will match anything (including the empty string, as Junuxx points out).

The chosen answer is slightly incorrect, as it wont match line breaks or returns. This regex to match anything is useful if your desired selection includes any line breaks:
[\s\S]+
[\s\S] matches a character that is either a whitespace character (including line break characters), or a character that is not a whitespace character. Since all characters are either whitespace or non-whitespace, this character class matches any character. the + matches one or more of the preceding expression
