They are not calling the inherited constructor.
As a result, LoadFromFile() will crash, since no default encoding is present.
(the default encoding is set in the constructor)
Unless you know what you are doing, you must always call the inherited constructor,
if there is one. You must give the parent class the chance to initialize itself
correctly. It's not because a particular constructor is empty today, that it will be
empty tomorrow.

<p>Hello!</p>
<p>What if the line "inherited;" is automatically included when
using code completion (<Ctrl><Shift>C) for
constructor, destructor, CreateForm, DestroyForm, etc.? Instead of</p>
<blockquote>
<p>begin</p>
<p>end;</p>
</blockquote>
<p>it may be</p>
<blockquote>
<p>begin</p>
<blockquote>
<p>inherited;</p>
</blockquote>
<p>end;<br>
</p>
