However, JA subtitles uses font shearing to simulate italics; indicating, for example, that the speaker is offscreen.  We consider oblique text to be an essential JA subtitle feature that we see in the [Videotron] Lambda CAP JA subtitle assets that we ingest, 

Yes, this seems a classic case of a feature that should be generally supported in CSS for all (at least Japanese) text. I am puzzled that it is not. Is fontShear more common in, or only used in, subtitles or is it generally used in Japanese typography as well?

I am sure that the subtitle domain would be welcoming a better integration of their requirements in CSS. This maybe a process that needs some more time and parallel developments may only be a mid-term phenomenon of the conversion process. I am convinced that next TPAC could help to speed the process with productive discussions and group agreements.
