Jquery select2 regex plugin for valid characters?

Is there a way to define a set of valid characters for user input? E.g. alphanumeric input only. It doesn't seem to be found in the official documentation.

You can accomplish this using the createSearchChoice parameter, which allows you to define a user-defined function to create tags from user input. To prevent tags containing non-alphanumeric characters, select2 should be initialized as follows:

$("#mySelect").select2({
            createSearchChoice: function(term) {
                if(term.match(/^[a-zA-Z0-9]+$/g))
                    return { id: term, text: term };
            },
            formatNoMatches: "Enter valid format text"})

, - , select2 . NoMatches, , " ", , .

Update:

select2 ~ 4.0 createTag

select2("container") , select2("dropdown") ( ).

So my last code (for the purpose of contribution):

$('my-select2').on('select2-open',function(e){
    var input = $(this).select2("dropdown").find('.select2-input');
    // ...
});
