Changing é into html entities without touching the html elements ?

[Peuplarchie]

Good day to you all,

          I'm working on a script which take the text from a txt file and add his content to an php page.

          I have no problem with that part, see code below :

 

$textsec = file_get_contents('text.txt');
echo nl2br($textsec);

 

 

This page can include <b> <u>... html element.

 

Where my problem start is that it's possible that I get some :

é
à

..words with accent..

 

How can I convert them to their respective html entitie code without touching my html element ?

 

Thanks!
