FString HexCode = “0041”;
char* _HexCode = TCHAR_TO_ANSI(*HexCode);
wchar_t wc = strtol(_HexCode, NULL, 16);

FString UtfChar = "";
UtfChar.AppendChar(wc);

If you have better solution let me know.

I don’t know if it is better or not but

bool UExtendedVarsBPLibrary::Hex_To_String(FString& Out_Decoded, FString In_Hex)
{
    if (In_Hex.IsEmpty())
    {
        return false;
    }

    for (size_t Index_Chars = 0; Index_Chars < In_Hex.Len(); Index_Chars += 2)
    {
        //taking two characters from hex string
        FString Part = UKismetStringLibrary::GetSubstring(In_Hex, Index_Chars, 2);

        //changing it into base 16
        char Character = std::stoul(TCHAR_TO_UTF8(*Part), nullptr, 16);

        //putting it into the ASCII string
        Out_Decoded += Character;
    }

    return true;
}
