How can I see if legal anime subs are available in a certain language for streaming?
I have found a solution. On Crunchyroll there is a workaround to this.



Step 1

Head over to the footer or bottom of the website. It should look something like this >



Step 2

From the footer, head over to languages in the footer, then head over to the highlighted text which says 'French'



Step 3

After this the page should reload and the animes should now be playing with French subtitles.

Note: Not sure if it will work, but it did work for me. Have a look in the picture below. Try it on Golden Time Episode 24.
