FiraSans 3.108 - glyphs with negative advance widths about fira

[patrykdesign]

@jfkthame We can't see the glyphs in this report... Ralph thinks these must be combining accents. He says: "Combining accents do have a negative width if the shape is place left to zeroline.
We do that, cause these accents this way also work more or less fine without mark positioning."

[jfkthame]

Huh, I thought I fixed that once already. Github doesn't like the angle-brackets from TTX output, so I've replaced them with [square brackets]. Hope the edit survives this time!

These aren't combining accents, they're glyphs like zerowidthspace that should have a zero advance width but actually have a negative advance -- i.e. they'll try to "backspace" a bit.

This isn't about placement of an accent glyph relative to the origin; that's a different matter (but even then, although the glyph outline may be at negative x-coordinates, its advance width will still be zero, not negative).

will check that. this should be solved via an export parameter if could not find a bug in my work files.

[jfkthame]

I'm still seeing these glyphs with negative "advance" in the 3.109 version.

[jfkthame]

In 3.109, I notice that FiraMono-Regular.otf also has a couple of glyphs with negative advance:

<mtx name="null" width="-80" lsb="0"/>
<mtx name="zerowidthspace" width="-80" lsb="0"/>

These should both have width="0".

@jfkthame should be fixed in v.3.110

[patrykdesign]

@jfkthame can you please verify?

[jfkthame]

I just looked at FiraSans-Italic (in both .otf and .ttf formats), and it still has the same collection of glyphs with negative advance. :(

[jfkthame]

The problem in FiraMono-Regular does appear to be fixed, however.

[carrois]

Georg just send over a newer build of Glyphs2 _beta which should fix that. give me an hour or two.

[carrois]

If so ... the version number (a cool one) 3.111 will be available today.

[carrois]

checked againFiraSans-Italic (in both .otf and .ttf formats), and could not find negative width glyphs anywhere.
no problem to update once more if needed but please check 3.110 once more on your side too.
Thanks.

[patrykdesign]

fixed with v.3.111
