upon converting text using 'object to path', not all of the smooth nodes are 'smooth'
this is a re-issue of https://bugs.launchpad.net/inkscape/+bug/276135
not all of the smooth nodes show up as being smooth.
the attached .svg file has a 'G' in Arial and a 'G' in Times New Roman. Both were converted using Path | Object to Path. The nodes that should be smooth, but are not smooth, have been circled with a green line.
Normally this would not be a major problem; however some applications use smoothness tests to determine whether to generate a continuous multispline, or create a new spline. If you export this to .dxf using the ROBO Master option then it leads to discontinuities in the multispline.
