The problem with unicode is that you cannot be sure that there are always 4 digits per character.<br />

string oldString = &quot;003800380038&quot;;<br />

string oldString = "003800380038";
string newString = "";

for (int i=0; i < oldString.Length;i++) .{

Sorry.. I hit the wrong keys so it was sent too early. I would try something like this:<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string oldString = &quot;003800380038&quot;;<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string newString = &quot;&quot;;<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; while (oldString.Length &gt;= 4) {<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; newString += (&quot;\\u&quot; + oldString.Substring(0,4));<wbr /><br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; oldString = oldString.Substring(4);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }
</div>

            while (oldString.Length >= 4) {

                oldString = oldString.Substring(4);

Sorry I have been too vague.<br />
The problem is not adding the escape char. The problem is getting the string converted to &quot;8888&quot;. If I would output newString it would just show &quot;\u0038&quot;.<br />
All Unicode (utf16) characters are represented by hexadecimal numbers from 0000 to FFFF (in my case).<br />

I just can't get this working.<br />
<br />
I have a string read from a source, for example &quot;0038003800380038&quot; which is Unicode. Thing is that the Unicode escape character is missing. I want to convert it to ASCII (8888). How do I do it?<br />
<br />
&quot;0038003800380038&quot; -&gt; &quot;\u0038\u0038\u0038\u0038&quot;<wbr /> -&gt; &quot;8888&quot;

"0038003800380038" -> "\u0038\u0038\u0038\u0038" -> "8888"

C#, problem with Unicode conversion. (.NET 4)

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
