lnum and tnum features in SourceSans3?

[dr-scsi]

Hi all,

I checked for the features provided by the latest SourceSans3 fonts (v3.046) with otfinfo and get this:

I'm not an expert on this, but is it possible that lnum and tnum features are missing? This is a problem for applications relying on them (I stumbled over it by trying the fonts with lualatex and the fontspec package). The figure versions themselves are there.

[pauldhunt]

the default figures are lining (lnum) and tabular (tnum) by default, so in order to access lining tabular figures simply don’t apply any figure styles.

Thanks for your response. Is it then possible to turn this question into a "Feature Request"? It would be helpful when one is writing a LaTeX document (compiled with lualatex and with the fontspec package) and want to change the fonts locally. Currently, one has to write code like this:

{%
  0123456789\\
  \addfontfeatures{Numbers=OldStyle}0123456789\\
  \addfontfeatures{Numbers=OldStyleOff}0123456789
}

where something like this feels more natural:

{%
  0123456789\\
  \addfontfeatures{Numbers=OldStyle}0123456789\\
  \addfontfeatures{Numbers=Lining}0123456789
}

The second version throws the following warning:

Package fontspec Warning: OpenType feature 'Numbers=Uppercase' (lnum) not
(fontspec)                available for font 'sourcesans3-regular' with script
(fontspec)                'CustomDefault' and language 'Default'.

which is of course true.
