[Bug report/Question] Unicode tab-names links don't work

[PavelPancocha]

Hi!

Problem:

If your tab name has any Unicode chars, it works as expected till you want to use the generated URL to access that tab directly.

E.g.: The tab "Oprávnění" generates this: #oprávnění-tab - If I try to go to this URL directly I end up on the first tab ("Obecné" in this case). If there is a tab only with ASCII, it works great.

Question:

Why there is the allow Unicode option ON on slugify? Apart its name unicode_slugify :) https://github.com/farridav/django-jazzmin/blob/a69840caa7639daee8400710a877038efa1a7cc1/jazzmin/templatetags/jazzmin.py#L538

Using only ASCII chars in href seems to solve this. https://github.com/farridav/django-jazzmin/blob/6c6f88c8cacacf3f6dfae7aacee17e644eb4c39f/jazzmin/templates/jazzmin/includes/horizontal_tabs.html#L8

Is there some real usage, that needs to be Unicode? If yes, can there be another slugifier for generating tabs ids/href that will return only ASCII?
