I love the (unicode) Neo Euler font from Hermann Zapf & Khaled Hosny. The only caveat is the \sum
symbol, which is in my opinion just ugly:
I hear it also from other people, therefore I wonder if someone designed an alternative sum symbol for Neo Euler?
I am aware, that I could load this symbol from the other unicode math packages (Cambria, Asana, XITS, LM, Lucida, Latin Modern, TeX Gyre), but they don't look nice with Neo Euler.

One possibility is to use my technique at How are big operators defined? to define
\varsum
, which takes the\Sigma
glyph from the same font family and scales it to the size of\sum
.This approach has the advantage of using a glyph already in that font family. However, you may find the weight too heavy is the downside.
Note that I don't have the neo Euler font, so I demonstrate below with the
eulervm
package. After showing the\Sigma
glyph on the first line, I then compare equations using\sum
and\varsum
in all math styles.And here is a version that takes the
\Sigma
glyph in\scriptstyle
by defining\varsum
asIt produces a wider result
