Accessibility: Add button for subtitles with official "CC" logo

[cgruber-uos]

We have the subtitle-logo-discussion also with OC Editor, see https://github.com/opencast/opencast-editor/issues/897

I would propose to not use the cc-logo because "closed captioning", what cc means, is an English term and not so universal understandable, e.g. in German speaking television we have the UT logo (DE "Untertitel" = subtitle) as icon. A more universal, not language related logo would be:

YouTube is using this also:

For OC Editor we have planed to use the Icons form the React iconset: https://react-icons.github.io/react-icons/search?q=subtitles

Thanks, Clemens. I'm a bit surprised (at YouTube's decision) and others (Vimeo, http://www.mediaelementjs.com/) use CC. I've raised the issue with colleagues from ZHAW who did the accessibility review.

It seems YouTube uses a CC symbol in native English-speaking areas, cf. https://tinyurl.com/2krmqr6m. Given we won't have that much flexibility, we might use what they use for the rest of the world. Oriane is also fine with this.

This is a 4 year old video, so I think it was that time the case but is the no more, have a look e.g. at https://www.youtube.com/watch?v=Ad_TEk94B9Q there is also the new one, also in the YT backend:

Interesting. https://support.google.com/youtube/answer/2734796?hl=en&ref_topic=7296214 is the current explanation on how to add subtitles and it shows a CC symbol...

However, if you open the video directly (https://youtu.be/rB9ql0L0cUQ), it shows "the other symbol". Which makes it alright to use it, I guess.

Could you make

look more like the one discussed?

? This one reminds me of slides and their content...
