Comment puis-je HTML encoder une chaîne et utiliser des balises encodées lisible par l'homme (ex: ê au lieu de ê)

Bonjour, je suis à la recherche d'un moyen d'encoder une chaîne en HTML qui utilise des balises lisibles par l'homme tels que ê (= ê). À l'heure actuelle, j'utilise la fonction HttpUtility.HtmlEncode(), mais il semble renvoyer des balises numérotées au lieu de celles lisibles par l'homme. Par exemple:Comment puis-je HTML encoder une chaîne et utiliser des balises encodées lisible par l'homme (ex: ê au lieu de ê)

Dim str as string = HttpUtility;HtmlEncode("vente - en-tête") 
'Expected: vente - en-t&ecirc;te 
'Actually received: vente - en-t&#234;te

est-il un paramètre ou une fonction dans ASP.Net pour encoder une chaîne en HTML ressemblant au premier commentaire?

EDIT: Je recherche ce type de fonctionnalité car le texte est enregistré en HTML dans la base de données. Le texte provient d'un tas de documents MS Word qui ont été convertis en HTML.

Je ne l'ai jamais trouvé une telle fonction et je suis assez sûr qu'il n'existe pas bien que ce serait bien. J'ai toujours fini par rouler le mien. Ne devrait pas être trop difficile à analyser http://www.w3.org/TR/html4/sgml/entities.html et écrire une cartographie. –

Je me demande quand exactement ce serait nécessaire de toute façon –

Je suis curieux de savoir pourquoi il est important qu'ils soient «lisibles par l'homme» ou non - le navigateur ne s'en soucie pas, et c'est sûrement la seule considération? –

est ici une fonction qui fait le travail:
