Javascript string searching, double dot appears over the letter i

Question

I'm trying to search a string variable (a city name that comes from an array) in another string (an address string). Here is the sample code :

    var cities = [....];
    var address ='....';
    var cityName ='';

    for(var i=0; i < cities.length){
        cityName = cities[i];
        console.log(cityName);

       if(address.search(cityName) > 0){
        return cityName;
       }

   }

But, even though there is not a special character problem in the cityName , search method returns -1 for an existing cityName.

Because, when i copy the cityName from the console and paste it to the js file again, it appears double dot on the i letter (i couldn't write here, it turned to normal i) so the method cannot find the city.

Is it an encoding problem or what?

S.O.S

Help us identify the problem here? `"ï".indexOf("i") === -1`...If you search for `ï` is will find it and if you search for `i` it will not. They aren't the same letter. — Malk, Aug 24 '16 at 21:13
Maybe you could sanitize the address and the cityName by replacing any accentuated character, before searching. Have a look at this: http://stackoverflow.com/questions/990904/remove-accents-diacritics-in-a-string-in-javascript — blex, Aug 24 '16 at 21:19
Yes, but why is it happening? There's no any special characters both in the array and the address. — Ozgur O., Aug 24 '16 at 21:25
@OzgurO. `"Hï".search("Hï")` works. So you are probably trying to look for a single dotted i. `ï` and `i` are two distinct characters, so `"Hï".search("Hi")` won't work — blex, Aug 24 '16 at 21:32
replaced the character with normal i then the problem solved. But it is for just one character. Pretty sure i'll be facing another character issues. Thank you all. — Ozgur O., Aug 24 '16 at 21:49

Not sure I understand your problem right, but I'm assuming it's caused by a dieresis ("double dot on the i")? If so you might need to look into encoding those characters, here are the encoding for an i with dieresis

Ï \xCF Ï Ï %CF %C3%8F latin capital letter I with diaeresis

ï \xEF ï ï %EF %C3%AF latin small letter i with diaeresis

Yes it is the problem. But the character is a little different. Like one dot over another dot. And how can you paste the special characters here? I checked the help for the comments but i couldn't find a way – Ozgur O. Aug 24 '16 at 21:29
