I have the link containing %3A symbol:
<a href="https://it.site.com/place/?symbol=TVC%3AFTMIB" target="_blank" rel="noopener">text</a>

How to put the link corretly inside RSS’s description tag?

<rss version="2.0">
    <channel>
        <title>Noticias ahora</title>
        <link>https://www.europapress.es</link>
        <description>Noticias de actualidad</description>
        <language>es-ES</language>
        <item>
            <guid>GUID</guid>
            <title>TITLE</title>
            <description><![CDATA[
 
]]></description>
            <category></category>
            <link>LINK</link>
