Inconsistency in variant uppercase Upsilon forms #215

Open tiroj opened 2 years ago

tiroj commented 2 years ago

As reported by @PaulHanslow

The Upsilon's italic form (/u1D6F6) is a different shape to its ssty form. The former has the more cursive construction with the ball terminal on the top right, while the SSTY and SSTY2 versions are the regular italic Y construction. It gets a little confusing as there is both forms of Upsilons in the upright, the typical Y form (/03A5) and the upright cursive form (/03D2). I can confirm that Microsoft Office uses the italic form (/u1D6F6) for italics, while the SSTY is using the italic Y form. Below shows /u1D6F6 and its SSTY1 & 2 forms.

Add glyphs to provide consistent variation between Upsilon forms across alphabet styles with corresponding ssty variants.
