Comment bien gérer les caractères accentués dans les pages HTML

ISO-8859-1 ou UTF-8/16.

Quel encodage choisir pour afficher correctement tous les caractères accentués qu'il y a dans la langue française ?

Tous les caractères accentués de la langue française sont gérés par la norme ISO-8859-1.

En HTML, il y a une astuce qui consiste à ne pas s'occuper du type de l'encodage des caractères mais utiliser à la place le nom d'entité des caractères (entity name).

Grâce à cette technique, tous les caractères seront toujours affichés correctement.

Par exemple, au lieu d'écrire ceci dans une page HTML

<html>
<body>
<p>Ceci est un caractère accentué</p>
</body>
</html>

Qui pourrait provoquer un problème à l'affichage si le codage des caractères est mal défini (comme ceci)

Ceci est un caractère accentué

Il vaut mieux écrire cela

<html>
<body>
<p>Ceci est un caract
&egrave;re accentu&eacute;</p>
</body>
</html>

Ce qui donne comme résultat

Ceci est un caractère accentué

Plus besoin de se soucier de l'encodage du fichier.
