As far as I got it they are open type features to select variants of
characters and are used as any other open type feature:

;+cv01=0;+cv02=0;+cv03=0;+cv04=0;+cv05=0;+cv06=0;...

In the bug report the problem seemed to be that the user used so
many of this features that some string got too long. 

But due to the other error I couldn't look at it yet.

What are character variants? Anyway, if it's "features" there is no 
relation between choosing features and loading a font.

Hm, another of these N x M instance fonts generated from a common

[NTG-context] fontloader fails with "bad argument #1 to 'for iterator"

2018-08-18 Thread Ulrike Fischer

On the luaotfload tracker was a bug report that the loading of a
font failed if too many character variant were requested

https://github.com/lualatex/luaotfload/issues/424

I wanted to check if the problem still exist with a current
fontloader. Here (both context and latex) the loading of this fonts
fails even if no character variants at all are requested:

\starttext

\font\x={file:iosevka-type-slab-regular.ttf}
\x

ablub
\stoptext 


gives 
...ext/tex/texmf-context/tex/context/base/mkiv/font-oup.lua:2137:
bad argument #1 to 'for iterator' (table expected, got nil)


The font can be get from 

https://github.com/be5invis/Iosevka/releases

it is in the 07-iosevka-type-slab-2.0.0.zip.
