On Windows XP with ClearType on, Lucida Sans Unicode looks great. With standard smoothing, however, at some point sizes the hinting causes the P to be off-center within the circle. MS Reference Sans Serif does better when ClearType is off. I haven't seen what it does with ClearType on.

Analysis

When the requested font is not available, I believe Firefox selects the first font, in alphabetical order, that contains the glyphs. So in my case it uses Arial Unicode MS for the missing fonts. Update: After installing Code2000, it started using that, so perhaps Firefox is choosing the most-recently installed font.

OS no smoothing smoothing ClearType
Windows XP Lucida Sans Unicode looks good, but at some sizes, hinting causes P to be off-center within the circle. Lucida Sans Unicode looks great.
Windows 2000 MS Reference Sans Serif looks great. Arial Unicode MS looks good at 7, 8, 9 and 11 pt, but other sizes have hinting irregularities. Lucida Sans Unicode looks good, but at some sizes, hinting causes P to be off-center within the circle. Code2000 has many pixels missing at all sizes under 13 pt. Code2000 and MS Reference Sans Serif look great. Lucida Sans Unicode looks good, but at some sizes, hinting causes P to be off-center within the circle. n/a

MS Gothic / MS PGothic / MS Mincho / MS PMincho have no hinting or smoothing, so they're basically useless.

Availability

Lucida Sans Unicode should be available on all Windows 98, 2000, XP systems. Not on Windows ME. Server 2003 and Vista status unknown.

Lucida Grande is the equivalent of Lucida Sans Unicode on Mac OS X.

MS Reference Sans Serif will only be present if Encarta or Office 2007 is installed.

More fonts to try

  • Recent versions of DejaVu Sans
  • Lucida Grande on Mac OS X
  • Lucida Sans (comes with StarOffice, JRE, maybe OpenOffice?)
  • various other pan-Unicode fonts with Letterlike Symbols support - see http://www.alanwood.net/unicode/fonts.html
