Thanks for the instructions. In the Ubuntu font, U+25D3 maps from DejaVu Sans. Same for Arial, Garamond, Lucida Sans, Microsoft Sans Serif, Ubuntu Mono, Ubuntu Condensed, and dozens of others I tested. Serif and Times New Roman map U+25D3 from DejaVu Serif. Most monospace fonts map from DejaVu Mono and are fine.
So it seems that the problem is with these two fonts:
* DejaVu Sans
* DejaVu Serif
