Is it possible? I want to check if a string is utf-8 encoded.

UPDATE: So, the problem is: I have a php webservice. This webservice has a method that receives a string. I'm trying to pass a VB.NET JSON string to this webservice. json_decode always returns an error, saying that the string is not utf-8. If I pass the string and convert it using PHP utf8_encode, the accents get wrong! How could I solve that?

  • How does your string look like? byte[]? Commented May 17, 2011 at 19:27

  • The only way I think will work without any third party tools is to just iterate over the byte array and test if it matches a known encoding. A great article with this is posted @ mobzystems.com/code/detecting-text-encoding.aspx Commented May 17, 2011 at 19:34

    A System.String is never UTF-8. It's UTF-16. Only the byte representation of a string can be UTF-8. Commented May 17, 2011 at 19:50
