I find an anomaly in the typesetting of $\square$ in the Cambria font. The $\square$ is significantly smaller then the corresponding filled squares like $\boxtimes$, etc.
Is this intrinsic to the Cambria font? Or is some encoding wrong? I tried lmodern and lucidaot and both give squares of the same size.
See the example below.

Hello Hans,
The bad news: I think it's the font. The good news: here comes
MetaPost to the rescue!
I don't have Cambria, so I plucked a cambria.ttf file off the Internet
somewhere, which contains both Cambria and Cambria Math. I don't know
whether you have the same file/version, so YMMV, but it does exhibit
the problem you describe.
According to the lovely and free FontForge,
* the WHITE SQUARE glyph (U+25A1) is 1060 units high
* the SQUARED PLUS glyph (U+229E) is 1630 units high (of which 230
below the baseline).
This is in Cambria Math — Cambria does does not have either of these
glyphs. I suspect the square size is a design decision: that the
designers decided they wanted the white square to match the letters
rather than the 'squared *' operators.
Anyway, here's a very close MetaPost approximation of the 'squared
plus' square, made by looking in with FontForge and copying the glyph
dimensions. (And then tweaking them because some things still didn't
look right; didn't manage to fix everything, alas.) It scales with the
font size.
Cheers,
Sietse

Thanks, this indeed produces a square more akin to boxtimes in Cambria. But the situation seems even worse than I thought. Under the 40pt fontsize it is apparent that lucidaot's square has a thinner outline then boxtimes. Of the three fonts I tried (cambria, lmodern, lucidaot) it seems lmodern is the only one doing it right.

Depends on what is required to 'do it right' --- the Unicode reference
doesn't mention any mathematical use for U+25A1 white square, so I'm
not sure that "must match squared plus glyph" is a requirement.
Perhaps the creators of Cambria expected the glyph to be used for
itemizations, or footnote marks.
Out of curiosity: what are you using the square for / what does it
stand for, that makes matching squared plus so important to you? There
might even exist some other glyph that is semantically more suitable.
Cheers,
Sietse
