Circumflex and diaresis misplaced on lowercase i

not on other vowels, nor on capital I, it seems, nor with other accents: but see this:

Inherited from STIX but this is an obvious bug (these accents are placed too far right.) Affects regular, italic, italic and bold italic.

sample lines in XITS and Nimbus Roman for comparison; the vowels below are all XITS

Actually, it seems that it's more that the i itself is too far left:

Can you provide the actual string, what application is this?

dbenjaminmiller commented

Not application-specific. This is an issue with the design of î and ï. Open up the font in FontForge and you will see the defect in these two characters.

khaledhosny commented

I see, I thought it is an issue with mark positioning (which we don’t handle), but I now see that the i part is displaced in these glyphs.

dbenjaminmiller commented

Yep. I would say it is a pretty big QC issue in French, and should probably be fixed in the release version quickly and not just the master … I'm just surprised it wasn't caught earlier.

dbenjaminmiller commented

I just checked, and Type1 STIX is affected as well. So the issue is ancient.

khaledhosny commented

I’m fixing them. Though I don’t see the urgency given how long they have been broken.

dbenjaminmiller commented

Fair if you don't, I suppose. I am a bit surprised that STI didn't catch them though

dbenjaminmiller commented

Issue still present in the italic and bold italic. Slightly more subtle but same problem.

khaledhosny commented

I did check these fonts and the accented i glyphs had the i at the same place as the dotless i (unless the dotless i is misplaced as well).

dbenjaminmiller commented

Just took a look. you're right that the base glyph is not misplaced. In these fonts, it seems that it is the accent, rather, which is off.

khaledhosny commented

That is probably subjects. I checked Times (that ships with macOS) and it is very close to XITS. Times New Roman is lightly different, but its accents are smaller too.

Background is Mac Times.

Which why I said very close, not identical. I don’t think it has to be identically placed and it does not look misplaced to me, but feel free to change if you strongly feel so.

Upon further inspection, the italic fonts seem fine in print.
