Did you find any workaround?

At present the only known workaround is to create PNG graphics outside of the .Net MAUI toolchain - which is counter to a core objective of .Net MAUI.

The SVG conversion is handled by Svg.Skia, which doesn't support tspan elements (according to the wiki). Your example image is using tspan.

Until tspan is supported, I think your best option is to use Inkscape to convert the text to paths: https://inkscape.org/doc/tutorials/advanced/tutorial-advanced.html

Thanks for the information. That's a disappointing approach to providing an "enterprise class solution for multiple platforms development". This seams to be more often than not the answer with .Net MAUI - it's broken.
