How to keep the brackets in the URL?

I have this in frontmatter:

doi: '10.14258/izvasu(2014)4.2-37'

I want to get this url in html

{{ with .Params.doi }}<li>DOI <a href="{{ . }}">{{ . }}</a></li>{{ end }}

But Hugo replace ‘(’ to ‘%28’ and not resolve address. I’ve tried all the features ‘| safe*’, but none of them keeps brackets in url.

try safeJS or htmlUnscape . More info in the functions list
