Rendering non-ASCII charcaters fails

Trying to PNG this SVG:

<svg xmlns="http://www.w3.org/2000/svg"><g><text x="50" y="50" font-size="15">åäö</text></g></svg>

...gets me this:

Confirmed this does not happen in Edge, Chrome, or Firefox despite there being no encoding declaration. So assuming I can repro with svg2png, it's our bug...

Hi! Looks like the problem happens when phantomjs parses Base64-encoded SVG from stdin with atob (see lib/converter.js). So the HTML passed to phantom for rendering has wrong characters.

I'm not sure, what is the best way to solve it. As a workaround, I can suggest replacing all non-ASCII characters to their appropriate HTML codes in your SVG:

svg = svg.replace(/[\u0080-\u024F]/g, v => '&#' + v.charCodeAt() + ';')

worked for me.

@losnikitos thanks for the diagnosis! It sounds like this is something svg2png should fix for people, e.g. by using a better base64 encoder/decoder. Now that I understand the issue better I can hopefully fix it soon, or maybe someone can send a pull request.
