Bootstrap 4 navbar toggle icon does not display correctly in Android.

Here is the screenshot.

In the red mark. It should be hamburger icon but in Android (Chrome), it is not.

My HTML

<nav class="navbar navbar-light bg-faded">
    <div class="container">
        <a class="navbar-brand" href="./">Template</a>
        <button class="navbar-toggler hidden-sm-up" type="button" data-toggle="collapse" data-target="#bs4-navbar-collapse" aria-controls="bs4-navbar-collapse" aria-expanded="false" aria-label="Toggle navigation">
            &#9776;
        </button>
        <div class="clearfix hidden-sm-up"></div>

        <div class="collapse navbar-toggleable-xs" id="bs4-navbar-collapse">
            <ul class="nav navbar-nav">
                ...
            </ul>
        </div>
    </div>
</nav>
<!--end navbar header--> 

Is there a way to make it display the same icon cross platform? (without any additional css like FontAwesome)

Fix is in next alpha (tl;dr: uses SVG rather than unicode character) #20329
