It would be nice if a shape’s character case setting from the shape sheet was respected, so that when case is set to visCaseAllCaps, all the text in the exported text is upper case (either by up-casing the text) or using CSS styling. Same goes for visCaseInitialCaps.
See the attached zip for an example of the problem. You’ll see the case is shown properly in the Visio generated SVG, but not in the Aspose SVG.
