std::string and Unicode problem

Recommended Posts

Is it possible that std::string find() function will not recognize certain characters? For example:
std::string test = "☺VERSION☺";

int result = test.find("☺");

//result always equals (-1) meaning it didnt find it

ok its formatting it into some WEIRD garbage here on the board, buts its a small smiley face type character.... thanks

Are you sure your giving us the exact code as above because this works:

#include <string>
#include <iostream>

int main() {

std::string test("&#9786;VERSION&#9786;"), key("&#9786;");

std::string::size_type result = test.find(key);

if(result != std::string::npos)
std::cout << "found at pos: " << result << ", word: " << test.substr(result, key.length()) << std::endl;
std::cout << "Not found" << std::endl;

return 0;


All of those characters are in ascii character set, you don't need wstring unless you are going to use wide characters but i don't see that being the case.

He's not trying to search for any of the characters in the ASCII string "&#9786;". He's trying to search for the UNICODE character ☺, who's HTML entity is "&#9786;". He formatted it that way for this forum.
