Some details: eth and thorn are used in differential geometry as mathematical symbols. There is an apparent shortage of d-like symbols in this field. Arrangement of the font tables (and this argument goes really LaTeXy) One could have essentially two points of view on the table arrangement: a) Providing optimal kerning for a core of 256 glyphs. This would lead to a mixture of upright and math italic glyphs in one table together with basic braces. b) Logical markup (more on the LaTeX path but sacrificing optimal kerning): Make \mathrm{\pi} work (like \mathrm{\Pi} etc. already do work). This means sorting out the glyphs according to their fontshapes in different mathematical familes. Note that the question after \mathbf{\pi} is an FAQ on comp.text.tex and it is tedious to tell the users again and again to use boldsymbol on that, whereas \mathbf{\Pi} works fine. --J"org Knappen
