[RESOLVED] How to convert emoji's unicode strings

[vuyiswamb]

Good Day All

i have a unicode character which works very well

/// Thinking face 🤔
/// </summary>
UnicodeString Thinking =0x1f914;

as you can see the value here is "0x1f914"

so i use this site which has a list of emoji's [Full Emoji List, v12.0](http://www.unicode.org/emoji/charts/...moji-list.html)

but the code in that website is "U+1F914"

how do i convert U+1F914 to 0x1f914 in c#

thanks

The '0x' is part of the code, not part of the value. It's just how hexadecimal literals are indicated in code, just like double quotes around text indicates a string literal and single quotes a char literal. If you want a string that contains "U+1F914" from that number then you would use something like this:

var text = $"U+{number:X}";

or:

var text = "U+" + number.ToString("X");

The 'X' format specifier indicates upper-case hexadecimal.

Hmmm... I think I may have misinterpreted the question and got it the wrong way around. Are you saying that you want to get a number from the text? If so then something like this:

var number = Convert.ToInt32(text.Substring(2), 16);

or:

var number = int.Parse(text.Substring(2), NumberStyles.HexNumber);

After i looked closely on the string , with lack of knowledge of the unicode stuff , i realized i just needed to replace the character and the emoji will be translated , the code below simply solved the problem

        txtresults.Text = txttext.Text.Replace("U+", "0x").ToLower();

Hello , @vuyiswamb

Please try this code,To convert emoji's unicode strings:

var convertStr = string.Join("-", Regex.Matches(res, @"..").Cast<Match>().ToList());
String[] tempArr = convertStr.Split('-');
byte[] decBytes = new byte[tempArr.Length];
for (int i = 0; i < tempArr.Length; i++)
{
    decBytes[i] = Convert.ToByte(tempArr[i], 16);
}
String str = Encoding.BigEndianUnicode.GetString(decBytes);

I hope this code will be usefull for you.
Thank you.
