Discordant ∏ (U+220F N-ARY PRODUCT) and ∑ (U+2211 N-ARY SUMMATION), etc

[apodtele]

It is probably not a good idea to italicize ∏ (U+220F N-ARY PRODUCT) in URW Bookman. At least, it should be consistent with ∑ (U+2211 N-ARY SUMMATION). Nimbus Sans, Nimbus Sans Narrow, Nimbus Mono PS mess up baseline or size of these glyphs.

Also in URW Bookman, ϕ (U+03D5 GREEK PHI SYMBOL) is identical to φ (U+03C6 GREEK SMALL LETTER PHI). Usually the former has a closed form. This distinction might be important in some math formulas.
