Your path2.svg example shows a filled "e" in browsers and Inkscape too, so the path definitions it contains fill the "e" area, or maybe do not set proper fill-rules. What tool / code are you using exactly to "make SVG from text"? I use MindFusion.Diagramming.Wpf.Export.SvgExporter. Firstly, I exported text from diagram to SVG and add it to another diagram. After that, I exported to SVG the second diagram with this SVG. First SVG contains tag "text", but second export all with "path" with filled characters.

	SvgNode renders SVG <text> elements as paths indeed, due to them supporting separate stroke / fill, and some other effects. Then SvgExporter finds the paths in WPF visual tree and creates respective <path> markup. We guess we could add some special handling for solid-color texts to avoid the paths. Try this build for text bounds fix - https://mindfusion.eu/_beta/wpfdiag383.zip Regards, Slavcho Mindfusion

	Thank you for the update. Size the similar regardless of topleft. But if bounding box of text would be like as on pictures it stretches. I use ContentSize Fit. Can we export it with saving size of bounding box? Empty symbol, for example?

Could you give ETA, please?

	This build gives priority to the viewbox (which you can control using diagram.Bounds before exporting): https://mindfusion.eu/_beta/wpfdiag383.zip If you want to revert to using bounds of inner SVG elements, enable new SvgNode.ContentAutoBounds property. We have to release v383 this week, our developer will look into text/path conversions after that. Regards, Slavcho Mindfusion

	Hello! I want to clarify if conversions problem was fixed. And I've faced another problem with text on SVG node - text doesn't render weight other than default if I try to change it using TextAttributes.

	Oh, and there is a problem with text opacity as well. It seems like it is not taken into account the diagram is exporting.

	Quote: Hello! I want to clarify if conversions problem was fixed. And I've faced another problem with text on SVG node - text doesn't render weight other than default if I try to change it using TextAttributes. It's still imported as a path. Generally, we've implemented SvgNode to let people show SVG icons in their flowcharts, and not to create full-fledged SVG editors We 'll try to add import-as-text option for upcoming v3.9 release.

	Ah right, you had a custom node type that only draws text, and setting UIElement.Opacity on it? Our developer will check this scenario.

	Opacity works perfectly, thank you. But weight is still not imported.
