Regex to match ? from URL but not from query string

Question

Below is my regex to replace ? chars from a URL.

[?](?![-\w%+]+=|$)

Its working, but with some caveats. If the query parameter name contains characters which are not specified in the regx character set, it breaks.

Any suggestions ?

You can just use negated class

[?](?![^?]+=|$)

[^?] will look for any character that isn't ?
