Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment?
EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.
Here's a function that does the job :
public static string EntitiesEncode(string value)
{
if (string.IsNullOrEmpty(value)) return value;
var entities = new Dictionary<int, string>();
entities.Add(160, "nbsp");
