Need help on Regex to include European accents and special characters
<p>There are tons of articles here around but I wasn't able to find a solution in this case. </p>

<p>I need to <strong>exclude any strings that doesn't include European characters</strong> like Chinese, Arabic, Russian etc. </p>

<p>Is is possible with <strong>one single Regex</strong> to match:</p>

<ul>
<li><strong>Alphanumeric</strong> Latin Characters (<code>a,b,c,1,2,3,A,B,C ...</code>)</li>
<li>European <strong>Accents</strong> (<code>è,é,ò,ç,à ...</code>)</li>
<li>UTF-8 <strong>Symbols</strong> (<code>© ...</code>)</li>
<li><strong>Currencies</strong> (<code>€,£,$ ...</code>)</li>
<li>Whitespaces</li>
</ul>

<p>And exclude all other characters?</p>
