Reading scandinavian letters in strings

[Dovendyr]

Hello,
I must write a program that recognise scandinavian letters.
I wonder why this code does not work? (I use CLion 2018.)

for (char c: rad) {
       if(c == 'å')
           cout<<"Your text contains a " <<c<<'\n';
    }

I used the ASCII table [url="https://www.ascii-codes.com/cp865.html"]for scandinavian characters[/url] and tried:

[code]
for (unsigned char c: rad) {
if(c == 134)
cout<<"Your text contains a " <<c<<'\n';
}
[\code]

This does not work either. How can I solve it?

And how can I include all weird characters at once (once the initial problem is fixed)?
Could it be possible to write something like that?:

[code]
for (unsigned char c: rad) {
if(c >= 134 && c <= 165)
cout<<"Your text contains a " <<c<<'\n';
}
[\code]

Thank you.

Assuming that the strings you are dealing with are encoded in utf8, this will print the characters that are outside of the normal "ascii" range.

#include <iostream>
#include <string>

int main() {
    std::string s = "aäbcådeåxöhdøw";
    for (size_t i = 0; i < s.size(); ) {
        unsigned char c = s[i];
        if (c < 0xC0)
            i++;
        else {
            std::cout << s[i++];
            if (c >= 0xC0) std::cout << s[i++];
            if (c >= 0xE0) std::cout << s[i++];
            if (c >= 0xF0) std::cout << s[i++];
            std::cout << '\n';
        }
    }
}

Thank you, I get the principle I think...
