First look at Gentzen Symbol

So here is my first test that I've gotten working in LaTeX:

Gentzen prototype image

And for reference, here it is rendered with the "euler" package:

Euler reference image

I definitely have more to show, mostly I just need work out a manageable scheme for splitting my single OpenType font file into separate 255 glyph encoding chunks to make ye olde TeX happy. The oldstyle figures are not new, they are just  not normally the default in existing packages for AMS Euler. You may also notice I have increased the weight of some glyphs (like the brackets, parens, and plus in the above) as I think it makes the "color" a little smoother. Finally, I've been making rough fixes to the side-bearings and kerning. Anyway, I'd be interesting in hearing what people think so far.

    It looks nice, I really like the spacing and wheightier symbols, it makes things less diluted.

    I have a question about the ‘1’ though: the base line seems very big, won’t it look weird underlined?

    I like it, too, but I think I’d be curious to see it with the inside of the parens opened up a hair.

    As for the base of the 1, I guess I do not find myself underlying too frequently in mathematical formulas. However, whether to use oldstyle (text) figures or lining figures will be configurable in the end.

    Thanks as well 🙂

    By »opened up« do you mean less concave?
