I am building a blog and would like to have a line of social media icons immediately underneath the title. I have achieved this somewhat using the FontAwesome.

However I would like to include some icons not present in the toolkit. I have worked out that I could design my own icon as an SVG and make a custom font using the Icomoon app. However I am having trouble implementing this as is discussed in the related SO question.

It appears my original SVG is the problem and despite being a single layer on Inkscape the Icomoon app picked apart individual <path> elements in the SVG. From this and the fact that all the raw FontAwesome SVGs appear to have single paths I conclude that I too need a single <path> element SVG.

This is the icon I am trying to generate:

The way I see it there are three overlapping shapes in the image; the square, the pocket and the arrow. To demonstrate I have all the shapes here is each one individually:

enter image description here

I have then arranged the shapes into a single SVG like so:

Ultimately I'd like the shapes to be black, white and black respectively with white being the background as the shape is cut out from the shapes below it. However what this SVG actually looks like is:

enter image description here

and the shapes look black, black and white respectively.

Thus overlapping shapes can change from black to white (or cut-out), as is also seen in the raw FontAwesome SVGs (e.g. this one), but in this case it is not the right shape.

What determines this and how can I achieve what I'm after?

I turns out the keyword to google is "compound path" which led me to this blog post about the SVG fill-rule property. I have learnt that overlapping paths which go in opposite directions result in the interior path being cut out.

Looking at my shapes, the square, the pocket and the arrow, I observed they were being drawn in clockwise, clockwise and anticlockwise directions respectively. This explained why the arrow was being cut out but not the pocket.

I therefore followed this question and reversed the direction of the square so that they now went anticlockwise, clockwise, anticlockwise. I also set the M command from relative to absolute for each shape. This got me the desired SVG. Here is the final code:
