That would figure... printing the TextLayout.toString() yields:
[EMAIL PROTECTED]:0, len:16, cstart:0, clen:31,
chars:"50 61 72 74 6e 65 72 20 77 68 6f 20 68 61 73 20", level:0,
flags:0,font:java.awt.Font[family=Dialog,name=Dialog,style=plain,size=12],

I think I have a workaround... not tested it much yet, but it produces
text in SVG and the EPS version transformed form that by Inkscape is
excellent... basically by letting the TextLayout do all the work, and
then grabbing its values, I can use the drawString method, and get
text...
String slabel = "String of variable length";
AttributedString sas = new AttributedString(slabel);
g2.setFont(getCapFont());
AttributedCharacterIterator saci = sas.getIterator();
FontRenderContext sfrc = g2.getFontRenderContext();
LineBreakMeasurer slbm = new LineBreakMeasurer(saci, sfrc);
float swrappingWidth = (this.getXDimension()/4)-offsetunit;
float sx = offsetunit;
float sy = rowcentre1 -offsetunit;
int sstartchar =0;
while (slbm.getPosition() < saci.getEndIndex()) {
TextLayout stextLayout = slbm.nextLayout(swrappingWidth);
System.err.println("!! "+stextLayout.toString());
sy += stextLayout.getAscent();
//stextLayout.draw(g2, sx, sy);
g2.drawString(slabel.substring(sstartchar, slbm.getPosition()),
sx, sy);
sstartchar = slbm.getPosition();
sy += stextLayout.getDescent() + stextLayout.getLeading();
sx = offsetunit;
}
So far this seems to work... unless I've missed somehting obvious..?! ;-)

Apparently not - I'd got as far as Java > SVG > EPS, and EMF using the
freehep toolkit... the workaround preserves text in EPS too, assuming
inkscape isn't told to substitute outlines... illutrator gets confused by
the font names, but seems to make a sensible substitution.
Many thanks for your assistance!
Yours,
Matthew
