www.text returning strange value in Unity3D (C#)

Question

I'm using Unity 3D's WWW to make http requests: http://docs.unity3d.com/ScriptReference/WWW.html

It seems that no matter what kind of data I'm trying to access, it just returns: ���� every time. I've tried json files, I've tried php that just generates a string. I can't seem to access the values on the server.

C#:

public string url = "http://www.onelittledesigner.com/data.php";

IEnumerator Start() {
    WWW www = new WWW(url);
    yield return www;

    if (!string.IsNullOrEmpty(www.error)) {
        Debug.Log(www.error);
    } else {
        Debug.Log(www.text);
    }

}

PHP:

<?php
  echo "textiness";
?>

Note: I've used www.texture successfully to pull images off of the server. However, www.text doesn't seem to be working.

Copying answer from comment, with some additional tests. My results are in the comments. Note that using Default, ASCII or UTF8 does work on my machine - it also should on yours.

    // returned from www.bytes, copied here for readability
    byte[] bytes=new byte[]{116, 101, 120, 116, 105, 110, 101, 115, 115};

    string customDecoded=""; 
    foreach(var b in bytes)
        customDecoded+=(char)b; 

    Debug.Log(customDecoded); // textiness
    Debug.Log(System.Text.Encoding.Default); // System.Text.ASCIIEncoding
    Debug.Log(System.Text.Encoding.Default.GetString(bytes));  // textiness
    Debug.Log(System.Text.Encoding.ASCII.GetString(bytes));  // textiness
    Debug.Log(System.Text.Encoding.Unicode.GetString(bytes)); // 整瑸湩獥
    Debug.Log(System.Text.Encoding.UTF7.GetString(bytes)); // textiness
    Debug.Log(System.Text.Encoding.UTF8.GetString(bytes)); // textiness
    Debug.Log(System.Text.Encoding.UTF32.GetString(bytes)); // 整湩
    Debug.Log(System.Text.Encoding.BigEndianUnicode.GetString(bytes)); // 瑥硴楮敳

Please check if System.Text.Encoding.Default is ASCIIEncoding, maybe something changed the default value?
