How to create a PDF using XSLT with a *non commercial* renderer?

A library I am developing is supposed to create reports in PDF format with XSL transformation. A colleague recommended FO.NET[^]. However, FO.NET lacks several important features:

1. If a string is tool long for a table column or the page, there is no line break. All variants of keep-together are ignored. Wrap is ignored, too.

2. The option reference-orientation is ignored. There is even a warning that this feature is not implemented. However, the column titles must be rotated to save space.

3. The check mark "✓" is not displayed. A "#" is displayed instead. Note that the font does have the check mark.

I searched for commercial solutions. But even the cheapest solution is too expensive for the company I am working at.

Is there a PDF renderer free of charge that can be used along with a commercial (non open source) application?

What I have tried:

1. keep-together.within-column="always"
2. reference-orientation="90"
