This issue is mainly a problem when we do copy/past of method definition from the scripting documentation. The issue is that there are the char 'U+200B' between the method name and the parentheses.

This following tools can be used to see the issue: https://www.soscisurvey.de/tools/view-chars.php

So let's see a concrete example. Let's take this following method (copied from the scripting doc):

addAttachment​(XWikiAttachment attachment) 

If we put this in the [previous tools|https://www.soscisurvey.de/tools/view-chars.php] we have this:

addAttachmentU+200B(XWikiAttachment attachment)

We can also see this on the HTML code:

<span class="memberNameLink"><a href="#addAttachment(com.xpn.xwiki.doc.XWikiAttachment)">addAttachment</a></span>​(<a href="XWikiAttachment.html" title="class in com.xpn.xwiki.doc">XWikiAttachment</a>&nbsp;attachment) 

And if we put this in the [previous tools|https://www.soscisurvey.de/tools/view-chars.php] we can also detect it:

<span class="memberNameLink"><a href="#addAttachment(com.xpn.xwiki.doc.XWikiAttachment)">addAttachment</a></span>U+200B(<a href="XWikiAttachment.html" title="class in com.xpn.xwiki.doc">XWikiAttachment</a>&nbsp;attachment)  

This issue happen mainly for all method so it's a generic issues for all part of the scripting doc.
