Bounding Box accuracy for text containing ISO (Æ) characters

Hello, all.

I'm wondering if anyone could point me in the right direction re: coaxing
an SVGTextElement to return a correct bounding box when the text contains
ISO encoded characters.

SVGDocument doc = makeSvgDocument(svgString);

SVGTextElement svgTextElement = (SVGTextElement) doc.getElementById("textID"
);

svgTextElement.getFirstChild().setNodeValue("ΑΩ");

float width = svgTextElement.getBBox().getWidth();


My document is created as follows -

protected SVGDocument makeSvgDocument(String svgString) {

SVGDocument svgDoc = null;

@SuppressWarnings("unused")

GraphicsNode rootGN;

UserAgent userAgent    = new UserAgentAdapter();

DocumentLoader loader  = new DocumentLoader(userAgent);

BridgeContext ctx      = new BridgeContext(userAgent, loader);

GVTBuilder builder     = new GVTBuilder();

SAXSVGDocumentFactory factory = new
SAXSVGDocumentFactory(SAXParser.class.getCanonicalName(),
true);

try {

svgDoc = (SVGDocument) factory.createDocument("file:///dummy/dummy/file.svg",
new StringReader(svgString));

ctx.setDynamicState(BridgeContext.DYNAMIC);

rootGN = builder.build(ctx, svgDoc);

} catch (IOException e) {

e.printStackTrace();

}

return svgDoc;

}

It appears to me that the result (especially evident for width) is
calculated as if the 1 character is actually 6 characters.

Thank you.

Best regards,
