Asp.net - Convert Characters To Html Equivalent Using .net

I have a text document that is a roster of licensees. I am looping through this document to create a html table of this data. I've come across names with non standard characters.

This is one of them

Aimeé

I tried running all the inputs through the following function, but when it comes across the above character it doesn't replace it.

Function ReplaceBadCharacters(ByVal input As String) As String
Return input.Replace(Chr(233), "é")
End Function

How can I replace each character with the html equivalent?

EDIT

When I debug the above function it shows the input as Aime[] and not Aimeé.

In Chrome it looks like this Aime�
