How to draw text empty inside

I'm trying to draw some text (on a canvas element) with a "shadow" i.e. text empty inside and black around. I'd like to have this black quite "heavy", so I used lineWidth, but I'm obtaining a strange effect as you can see in the image (especially over the M).

How should I proceed?

My code:

 var text = "This is the canvas M";

 var canvas = document.getElementById('c');

 var ctx = canvas.getContext('2d');

 ctx.font = "24px Arial";

 ctx.lineWidth = 4;

 ctx.strokeStyle = "black";

 ctx.strokeText(text, 5, 30);

 ctx.fillStyle = "white";

 ctx.fillText(text, 5, 30);

 <canvas id="c"></div>

It's only a problem of Arial font ;) Try Calibri and the issue will be gone!

the only line I changed from ctx.font = "24px Arial"; into ctx.font = "24px Calibri";

Test it here.

UPDATE (also fix):

Also this will solve the issue with Arial:

 var text = "This is the canvas M";

 var canvas = document.getElementById('c');

 var ctx = canvas.getContext('2d');

 ctx.font = "24px Arial";

 ctx.lineJoin = 'round';     //ADD THIS LINE

 ctx.miterLimit = 2;         //& THIS LINE

 ctx.lineWidth = 4;

 ctx.strokeStyle = "black";

 ctx.strokeText(text, 5, 30);

 ctx.fillStyle = "white";

 ctx.fillText(text, 5, 30);

In your example i see a bad effect on the v, the drawing of the letter goes below the letter itself
