How to export SVG with right aligned text ?

How to export SVG with right-aligned text (Arabic)?
Below code generate left-aligned text :

var makerjs = require('makerjs')
var textModel;

opentype.load('fonts/Roboto-Black.ttf', function(err, font) {
    if (err)
    {
                alert('Could not load font: ' + err);
    }
    else
    {
		var text = 'Hello World! This box should start word-wrapping!';
                textModel = new makerjs.models.Text(font, text, 45, true, true);
		var svg = makerjs.exporter.toSVG(textModel,{stroke: '#000', fill: '#000'});
		document.write(svg);
    }

Start by tracing the makerjs.models.Text entry point and exporter.toSVG call shown in the example, then inspect how text positioning and SVG output are handled. The issue names no repository files or tests, and it does not define an acceptance criterion for right-aligned Arabic text, so the expected behavior would need clarification before implementation.
