How to turn off ˜~ˆ^ character substitution on MacOS?

Question

JavaScript

Hello everyone, please tell me how you can turn off the functionality on MacOS, which, when entering special characters from the keyboard, first waits for something, if you immediately write a character, it will be wrong, if you press the spacebar, then it changes to the correct one.
Here is an example
˜~ (different tildes)
ˆ^ (different triangles)
Because of this behavior, I can't even use the blog on Ghost, where the code input block appears when I press ```, but MacOS tries to replace my characters after I enter them, although in the settings keyboards are off...

It is necessary to sort through the available values ​​in a loop. It is more convenient to keep the data (strings) in an array of arrays:

data = [
    ["M166 E16", "A-Class", "2004", "A 160", "W168.II", "бензин"],
    ["M166 E19", "A-Class", "2004", "A 190", "W168.II", "бензин"],
    // и остальные данные. 
  ];

It is better to pull out the values ​​of the input fields only 1 time and store them in variables:

// вместо многократного
($("#class").val())
// лучше один раз
var _class = $("#class").val();
// и потом использовать значение этой переменной

General algorithm: we search by sorting through the lines. Once you find it, look no further. At the end, we look at whether something was found at all (we show) or not (we write “no results”).
The search raises questions:
Write a comparison with -1shorter as follows: !!~value- it will also be falseonly ifvalue == -1

$(document).ready(function() {
  const data = [
    ["M166 E16", "A-Class", "2004", "A 160", "W168.II", "бензин"],
    ["M166 E19", "A-Class", "2004", "A 190", "W168.II", "бензин"],
    ["M266 E15", "A-Class", "2005", "A 150", "W169.I", "бензин"],
    // и остальные данные. 
  ];


  $('.left').on('input', function() {
    const _class = $("#class").val(),
      _model = $("#model").val(),
      _god = $("#god").val(),
      _kuzov = $("#kuzov").val(),
      _tip = $("#tip").val()
    ;
    
    var index = -1; // сначала считаем, что "не найдено"
    
    for(let i = 0; i < data.length; i++) {
      let car = data[i];
      if( !!~car.indexOf(_class)
        &&  !!~car.indexOf(_model)
        &&  !!~car.indexOf(_god)
        &&  !!~car.indexOf(_kuzov)
        &&  !!~car.indexOf(_tip)
      ) {
        index = i;
        break;
      }
    }
    
    if(!!~index) {  // нашли и index стал больше -1
      $("#page-title").html( "Мотор " + data[i][0] );
    } else {        // не нашли и index === -1
      $("#page-title").html( "Нет такого" );
    }
  });
});
