In some help page I found that you can bookmark to save your work in sandbox.
I was surprised clicking on a bookmark brings me to my work not with all content. I have noticed that my content was up to the first non ASCII symbol - I used Lithuanian and Spanish letters with diacritics. I guess there is something in sandbox encountering a non-ASCII symbol when making an URL.
