These tables show some Unicode chars that have caused display problems with some programs. Along with the codes, they are shown here in the HTML &x___; notation, as a bare UTF-8 char, and as a GIF. The GIF files mostly come from unicode.com, though some were done via screen capture.

---

Some programs don't display these combining characters alone, while others will work if these characters are "combined" with a space and/or nbsp char. These codes do have official glyphs, and it should be possible to show them alone in textbooks and dictionaries.
