mb_substr as a solution for � works sometimes
<p>Hihi,</p>

<p>I used to get the symbol � at the end of a string which ended with special character...</p>

<p>I found the solution by adding mb_ to the "substr" which become (mb_substr)</p>

<p>It worked but every now and then it still appears and vanish in some cases if I refresh.</p>

<p>It there a permanently fix for this bug?</p>
