How to remove spaces between special characters

I have a requirement to remove spaces between special characters. I have a string:

abc = "test = > @ Stack overflow"

I want a string like this:

abc = "test=>@Stack overflow"

so that only spaces between, before, or after are removed. failed to create a proper regular expression or method for that. Any hint or idea?

You can use the following code:

abc = "test = > @ Stack overflow"
puts abc.gsub(/\s*([^\s\p{L}\p{N}])\s*/, "\\1")

See IDEONE demo, result: test=>@Stack overflow.

The capturing group is necessary to restore the captured "special" character.

The [^\s\p{L}\p{N}] stands for a non-whitespace, non-letter and non-digit character.
