assign it to myself to contact the contractor and see if they can fix this.

Fixed by latest update, #97

Are there binaries available for the latest delivery?

Yea, the TTFs in /hinted have been updated.

Sorry, I meant to mention this earlier, but the correct thin space used in French is supposed to be a non breaking thin space: U+202F narrow no-break space. Pretty much all the French typography guides say the thin space is non breaking.
Thin space U+2009 breaks and a line starting with a punctuation sign is not good.
So I suppose both U+202F and U+2009 should have the same advance width.

I’m not sure either where this “standard” of 1/8 em comes from, but it probably doesn’t matter at this point.

Lexique des règles typographiques en usage à l’Imprimerie nationale (1990), Code typographique (1993), Autour des mots (2005), Le Ramat européen de la typographie (2009) do not mention how wide the thin space is supposed to be but recommend its use in front of double punctuation (except colon), Le style du Monde recommends it for all double punctuation without mentioning its width either.

Le Ramat de la typographie (2008) mentions 40% of the space when trying to simulate the thin space.
Dictionnaire des règles typographique (2010) mentions that the 1/4 em is also called thin space
Dictionnaire typographique (2005) gives 1.5 pt for the thin space, 2 pt or 2.5 pt for the half space and 4 pt for the full space and then recommends actually using the half space (where one uses the thin space in the other guides).
Orthotypo (2005) mentions thin space 1 pt, pre-thin space 1.5 pt, half space 1/4 em and space 1/3 em.
Mémento typographique (1998) mentions “at least 2 pt” but says one can settle for 1/3 em when needed.
Orthotypo & Co (2013) also says the thin space is 1/4 em.

So basically, depending on where one looks, a French thin space can be 1/8, 1/6, 1/4, or even 1/3 em. The normal space’s width doesn’t seem to be standard either.

I find it boils down to personal preference amongst French typographers – the only rule of thumb is French-made fonts/books generally have tighter than other countries due to the space before punctuation – the French-made fonts I have have smaller thinsp, few have U+202F though it’s highly useful! (I suspect InDesign makes non-breaking space regardless of whether you use the non-breaking codepoint, otherwise more French fonts would have it).
