Re: square in Cambria font

["Meer, H. van der" <H.vanderMeer@uva.nl>]

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.
