I'm trying to convert a unicode 1 character string ♙ into a integer rapresentation of it but i can't seem to get it workign

this is what im currently doing
int check_piece_color(string piece)
{
int p = (int)piece[0];
return (p > 9818) ? 0 : 0;
}
it always returns -300
i also tried using wchar_t instead of int
but it seems that piece[0] is nothing

```cpp
int check_piece_color(string piece)
{
int p = (int)piece[0];

you need to learn about the internal representation of std::string first
an std::string variable is simmilar to std::vector<char> , but with one extra '\0' at the end of the elements
if you chose utf-8 to encode the bytes into text, different symbols might be encoded with 1, 2, 3 or 4 bytes
what you are trying to do here is to read the first byte (because you wrongly assume that your symbol is encoded with 1 byte) and check its code
this is wrong
first, dump the raw contents of this string variable to see what it looks like:
for(char c : piece)
{
cout<<(int)((unsigned char)c)<<"\n";
}
this will show you the code of each byte of your string, each byte being from 0 to 255
C++ standard library does not offer anything for utf-8 support, std::string is just a bunch of raw bytes

#include <iostream>
#include <fstream>
int main()
{
unsigned char whiteChessPawn_utf8[] = {0xe2, 0x99, 0x99};
std::ofstream writer("result_utf8.txt", std::ios::binary);
writer.write((const char*)&whiteChessPawn_utf8[0], 3);
}
and here is the raw binary contents, the same as the char array

do you understand now?
