Add possibility to type "/" in an answer (Fill in blanks)

Hi,

As an assistant in linguistics, I need my students to be able to write answers between slashes (/). This is very frequent, obvious and impossible to avoid, since International standard notation requires to put any given given phoneme between slashes (/).

So far, a "/" is used in H5P as a divider for alternative correct answers.

I came accross two topic/comment online about this issue (https://h5p.org/fill-in-the-blanks & https://www.sporcle.com/groups/topics/76d108fc9a49) but the answers were not satisfying: in the first link, the user gives up on using "/" this way ; in the second link, the suggestion that using "|" would display as "/" for the final user didn't work in my experience.

Thanks for your help.
