Unicode characters string

Question

I have the following String of characters.

string s = \"\\\\u0625\\\\u0647\\\\u0644\";

When I print the above sequence, I get:

Answer 1

Try Regex:

String inputString = "\\u0625\\u0647\\u0644";

var stringBuilder = new StringBuilder();
foreach (Match match in Regex.Matches(inputString, @"\u([\dA-Fa-f]{4})"))
{
    stringBuilder.AppendFormat(@"{0}", 
                               (Char)Convert.ToInt32(match.Groups[1].Value));
}

var result = stringBuilder.ToString();

Answer 2

I would suggest the use of String.Normalize. You can find everything here:

Answer 3

If you really don't control the string, then you need to replace those escape sequences with their values:

Regex.Replace(s, @"\u([0-9A-Fa-f]{4})", m => ((char)Convert.ToInt32(m.Groups[1].Value, 16)).ToString());

and hope that you don't have \\ escapes in there too.
