Hi I'm trying to transform a string containing special characters like û and ….

In my research and tests I almost succeeded using the following function:

public static string ToHex(this string input){    char[] values = input.ToCharArray();    string hex = "0x";    string add = "";    foreach (char c in values)    {        int value = Convert.ToInt32(c);        add = String.Format("{0:X}", value).Length == 1 ?             "0" + String.Format("{0:X}", value) + "00"             : String.Format("{0:X}", value) + "00";        hex += add;    }    return hex;}

If I try to decode ´o¸sçPQ^ûË\u000f±d it does it correctly and turns it into this 0xB4006F00B8007300E700500051005E00FB00CB000F00B1006400,

instead when I try to decode ´o¸sçPQ](ÂF\u0012…a it fails and turns it into 0xB4006F00B8007300E700500051005D002800C200460012002026006100 instead of this 0xB4006F00B8007300E700500051005D002800C2004600120026206100.

Making a minimum of debug I saw that the string is transformed from ´o¸sçPQ](ÂF\u0012…a to ´o¸sçPQ](ÂF.a, I wouldn't want that to be the problem but I'm not sure.

EDIT

I thank you in advance for every reply or comment,

A function which take input a ASCII string and output equivalent hexadecimal values, as:

uint8_t *fun_string2hex(char *str,uint8_t *hex){  uint64_t i=0,j=0;   /*converting str character into Hex */    for(i=0,j=0;i<strlen(str);i++,j+=2)    {          sprintf((char*)hex+j,"%02X",str[i]);    }    hex[j]='\0';    return hex;}

It works fine for small input length but very slow when input size increases.Is there some alternate solution or recommend some changes in function to speedup.

I'm using the Scanner class to get input from the console. I'm trying to get my input as integer(.nextInt()) but it does not accept any hexadecimal values. How can start my Program? How to take inputs as HexaDecimal Numbers and Process it?

I am trying to do convert to string to hexadecimal value in android.

for example:

String data= "C0819000001";

Expected result is:

byte[] b = {0x0C,0x30,0x38,0x31........0x01};

Please can anyone help on this one

I have a task to do. I get lot of data and my job is to decode it. Every piece I get is written in readable string of hex numbers. For example: "8a fd ff ff"

I tried with struct.unpack('<l', "8a fd ff ff") and I also tried a lot of way to decode and it would be too long to list. Only thing I know that this should give me -630 as a result.I don't know how the data was transformed to this form.

data = "8a fd ff ff"aa = np.array(list(data))print(aa)struct.unpack('<l', aa)

struct.error: unpack requires a buffer of 4 bytes

so the result should be -630. I tested it with an online hex decoder.
