COMBINING DOUBLE INVERTED BREVE (U+0361) causes characters to overlap

[andy-morris]

(I'm not sure if this is a bug in SCP or in OS X's font renderer, but it doesn't happen to other fonts.)

The character U+0361 seems to have somewhat wonky spacing behaviour. The sequence a͡bc in SCP has the 'a' and 'b' overlaid (and the tie symbol extending over the 'c' as well):

Can you please try to give as much information as possible about your working environment?:
OS & version, application & version, font version, &c.

Oh right. Sorry. 😅

• The font's version is 2.010.
• I'm using OS X 10.11.2.
• It happens in (the bundled versions of) TextEdit (1.11; whence the screen shot), Mail (9.2), and Notes (4.2), so it's probably not application specific. (But it might be related to the text renderer, so hopefully someone using another OS can chime in.) It happens in MacVim without the CoreText renderer, but with it, MacVim has its own bug which takes precedence. :)
• The other double-width breve accents aren't currently in the font, and I don't know of any other two-letter combining symbols to check, if there are any. So the problem is probably isolated to this one character.

There was a bug in this regard that will be remedied in the next patch release. However, there also seems to be buggy behavior in Mac’s handling of this particular character which causes the collapsing of character spacing that you are reporting. Therefore, the existing bug has been fixed, but this will still be an issue in TextEdit, Safari, and other apps that use the default Mac rendering. The issue is fixed in InDesign, Chrome, and Firefox.
