How do I replace url text with a symbol in the bibliography of a CV (moderncv class)?

Question

I want to include a link to my publication, using biblatex in a CV. But instead of the whole url, I just want a symbol which can be clicked.

My MWE is as follows:

\documentclass[11pt,a4paper]{moderncv}

% moderncv themes
\moderncvtheme[blue]{classic} 

% character encoding
\usepackage[utf8]{inputenc}                   
\usepackage{bbding}

% personal data
\firstname{John}
\familyname{Doe}
\title{}               
\address{somewhere}    

\email{some.thing@gmail.com}                      
\definecolor{linkcolour}{rgb}{0,0.2,0.6}            % hyperlinks setup
\AfterPreamble{\hypersetup{colorlinks,breaklinks,urlcolor=linkcolour, linkcolor=linkcolour}}

\usepackage{filecontents}
\begin{filecontents}{pubs.bib}
@article{cazier_whole-genome_2014,
    title = {My publication},
    volume = {5},
    url = {http://Somewebsite.html},        journal = {Nature},
    author = {Doe, John. and Smith, John},
    month = apr,
    year = {2014},
}
\end{filecontents}

\AfterPreamble{
\hypersetup{colorlinks,breaklinks,urlcolor=linkcolour, linkcolor=linkcolour}
}

\usepackage[backend=biber, doi=false, isbn=false, style=nature, maxbibnames=20, defernumbers=true]{biblatex}

\addbibresource{pubs.bib}



\begin{document}
\maketitle
\nocite{*}
\printbibliography[title={Publications}, type=article, resetnumbers=true]

\end{document}

What I have tried:

\AfterPreamble{
\hypersetup{colorlinks,breaklinks,urlcolor=linkcolour, linkcolor=linkcolour}
\let\orighref\href
\renewcommand{\href}[2]{\orighref{#1}{\ArrowBoldUpRight}} %I found this code on tex.SE
}

What I get:

As you can see, I get the little arrow replacing the email link. Whereas I want the url in the bibliography replaced with the arrow, without affecting the email link.

You should change the anything to do with the bibliography immediately before the bibliography, otherwise it would affect everything following the preamble as in your case.

\documentclass[11pt,a4paper]{moderncv}

% moderncv themes
\moderncvtheme[blue]{classic} 

% character encoding
\usepackage[utf8]{inputenc}                   
\usepackage{bbding}

% personal data
\firstname{John}
\familyname{Doe}
\title{}               
\address{somewhere}    

\email{some.thing@gmail.com}                      
\definecolor{linkcolour}{rgb}{0,0.2,0.6}            % hyperlinks setup
\AfterPreamble{\hypersetup{colorlinks,breaklinks,urlcolor=linkcolour, linkcolor=linkcolour}}

\usepackage{filecontents}
\begin{filecontents}{pubs.bib}
@article{cazier_whole-genome_2014,
    title = {My publication},
    volume = {5},
    url = {http://Somewebsite.html},        journal = {Nature},
    author = {Doe, John. and Smith, John},
    month = apr,
    year = {2014},
}
\end{filecontents}

\usepackage[backend=biber, doi=false, isbn=false, style=nature, maxbibnames=20, defernumbers=true]{biblatex}

\addbibresource{pubs.bib}


\begin{document}
\maketitle
\nocite{*}

\renewcommand{\url}[1]{\href{#1}{\ArrowBoldUpRight}}

\printbibliography[title={Publications}, type=article, resetnumbers=true]

\end{document}

In order to remove the surrounding <..>, replace \renewcommand{\url}[1]{..} above with

\DeclareFieldFormat{url}{%
  \ifhyperref
    {\href{#1}{\ArrowBoldUpRight}}
    {\url{#1}}}

as suggested in It there a way to make URL link in bibliography as one word `Link`?.
