User should have an account in order to log in and should have an add-on with kanji characters submitted.
āEdit Product Pageā, located on the left side, in the light blue square, should be highlighted.
āEdit Product Pageā is not highlighted.
Reproduced in amo-dev, amo-stage and amo-prod with Fx68, Win10x64.
Reproduced also for the āManage Authors & Licenseā and āManage Status & Versionsā links.
This issue is only reproduced when the "Add-on URL" has kanji characters.

@diox could you please transfer this issue to addons-server?
I think it's just https://github.com/mozilla/addons-server/blob/master/src/olympia/devhub/templates/devhub/includes/addons_edit_nav.html#L30 needs changing. I'd guess request.path is encoded somehow so non-ascii slugs don't match.
hi @madalincm ,will i can try to solve this issue as this is my first bug and want to solve this bug as quickly as possible
@harshsingla once you get a local instance of addons-server up and running let us know - you'll need it to test it works.

hi, @eviljeff as shown the edit product page is highlighted in the website as shown in the image ,you can check tell me what to do next .
thanks
@harshsingla the addon slug must contain non-ascii letters to replicate - the issue title references kanji (i.e. Japanese) but I suspect other characters may break it too (I replicated with some Korean)
@eviljeff sorry but i didn't get what you want to say ,are you talking about this.

No, Addon.slug in the model, which is exposed on the developer hub page as "Add-on URL". And, as I said, you need addons-server running locally to test the patch. This is not a good first bug if you don't know django already.
okay,but sorry i have window 10 home so i can't use docker that's why i didn't run it locally and can't do more.
thank you.
@eviljeff Could I ask you about running locally?
I finished install using docker. I ran docker. And I try to enter addons-server ("http://olympia.test" or "127.0.0.1" or "127.0.0.1:80" and so on). I can't run addons-server.
I wonder that Only me, I can't run addons-server locally.
Note.
I can run addons-frontend (http://olympia.test:3000). And I can see addons-frontend page on the browser.
check the nginx container is running (restart it if not); look in the /logs/ for other errors if ngnix is running.
@eviljeff Thank you for your info. I checked status and log.
Nginx container is terminated only like under status(docker-compose ps).

So, I can't run addons server.
I checked log about nginx log(docker-compose logs).
This problems relate to this Issue[0]?
If not it is, I gonna think more about my problem.
You can just restart nginx when that happens (docker-compose up -d again should do it for you).

Thank you!!
Thanks to your info, I solved my problem.
Sorry, I gonna be careful about tagging user.
I'm checking this problem now.
I made this case and saw the problem on product page. And I try to make this bug on test(local) site.
When I made this bug on local page, I can't make this bug locally. Because I met 500 error:)

I wanna reproduce on local app. Could you give me tips to make 'my New Add-on' locally?
It should work. You might have more information in the logs (found in the logs/ directory).
Hey I am interested in solving this issue. Please guide me.
Please read @eviljeff comments earlier in the issue for more information about how to fix this.
I checked 500 error on my app locally. And I solved. The reason is that not enough permission where directory is. The directory place is /code/storage/files/temp. (This is add-on storage locally)
I reviewed about this Issue. As @eviljeff said, this problem not same request.path and url (i.e addon.get_dev_url() value)[0].
e.g)
request.path (IRI) form: 
url (URI) form: developers/addon/%E8%99%8E-%E3%83%A9%E3%82%A4%E3%82%AA%E3%83%B3-test/edit
I have 2 methods to solve this problem.
This is url value change. I go to the get_dev_url() place and change format(uri -> iri) using uri_to_iri function.
(e.g uri_to_iri(django_reverse(viewname, urlconf, args, kwargs, current_app)) [1] )
But this method have a wide influence.
This is request.path value change. I use the template variable(made iri_to_uri() function) instead of request.path by adding variable to views.py [2].
I think that this method is appropriate.
If My thought is right, Could I work on it? or If I wrong, Could you give me tips better than this?
[2] https://github.com/mozilla/addons-server/blob/master/src/olympia/devhub/views.py
I think you're on the right path @junngo - changing get_dev_url() would affect too many places so we don't want to do that.
Adding a template variable is a better option (2) though it would need to be added to every view that shows includes the addon_edit_nav template (almost all of the single-addon views). Running uri_to_iri on request.path directly in the template would avoid that though I don't know of an existing jinja template filter to do that - it'd need to be the opposite of iriencode I guess. Do you know of one @diox?
it'd need to be the opposite of iriencode I guess. Do you know of one @diox?
Actually... @junngo mentions above that calling iri_to_uri() on request.path should fix it, so I think modifying the template to do <li {% if url in request.path|iriencode %}class="selected"{% endif %}> should work ?
I was looking for it.
That is urlencode template filter.
If I use urlencode tag, I can simply fix it on addon_edit_nav template.
The issue was verified in Amo dev with ff69 on Win10x64.
