The shape for lang=Greek is now consistent with Greek standard usage.

Hi Steve, good to know I've been of help to you, as you can see, I'm not always overburdening you with feature requests, sometimes, I also do my little homework ;)

Thanks--I was pretty confused about this.

I know in the past I had looked at such documents, but I remember being emphatically told the angular form was the only form used in real documents. I also suspect something changed in the standard over the years.

Also, I can see that I incompletely implemented a change: in the Extended range, some of the Upsilons are one style, others are the other. I think this was like my first year or so with this, and didn't have font features under my belt yet.

I've adopted a solution like that of the other situations where the standard shows a different glyph than the one normally used for Greek printing. For text identified as Greek, replacements are made of all the Upsilon combinations, so that the palm-tree form is used. This also involved some mark placement and kerning.

Ooops... actually I've got to eat my words... see http://citeseerx.ist.psu.edu/viewdoc/download?doi= page 8 paragraph 3.

and http://www.tlg.uci.edu/~opoudjis/unicode/letters.html paragraph 3.2 > Upsilon

Script kappa and Ypsilon with hook (that's how it's called) are both standard in Greece, so if we've made the choice of adopting the former as the default, we can't help but adopt the latter as well. It's also more beautiful to me ;) Latin-style Ypsilon can go into the character variant repository.

Yes it seems you're right. I have a vague memory of some argument about this, but can't find it now.
It's now more like the Unicode samples.

Actually, I've just remarked the shape is incorrect only in the extended Greek range, other the shape of YPSILON is good, that is, is homoglyphic with Latin Y.

Capital letter YPSILON should look just like Capital letter Y in the Latin Script. Sources:
