For example, when in my input in html i put a "testing - test" and i send this to my database in Oracle the register is like that : "testing ¿ test" . Why is this happening? I'm using javascript and Spring. Maybe is something of the configuration?

var minimoUnaLetra = /[A-Za-zÀ-ÿ\u00f1\u00d10-9]+/
        var denominacionComercial = $("#denominacionComercialTicket").val(); 
        if(denominacionComercial != ""){
            if(!minimoUnaLetra.test(denominacionComercial)){
                toastr.error("La denominación comercial debe contener, por lo menos, una letra o un número.");

                valido = false;
            }
            console.log("ANTES " + denominacionComercial);
            if(denominacionComercial.includes('–')){ 
                denominacionComercial.replace('–','-');
                console.log("DESPUÉS " + denominacionComercial);
            }
