Hi,
I like to add emojis in titles, but after an emoji is added, the url of the post also changes, including the name of the emoji.
For example, if I add the 
emoji, the url changes:
Before: www.example.com/t/nice-title/25
After: www.example.com/t/smile-nice-title/25
This is bad for SEO. Is there anyway to manually edit the URL or to avoid having URLs with emojis?
Thanks!
Iโve just added a emoji to the title of this post, and the url didnโt change. 
How do I achieve this in my installation?
I donโt think removing the emojis from the url is a possibility just yet, but I could be wrong.
While I understand you want to keep the emojis but remove them from urls, if that bothers you so much, you can remove / disable them altogether.
There was a bit of discussion about this here:
Which resulted in a setting to disable emojis in topic titles if thatโs what you prefer:
Thanks! I understand.
Anyway, there must be a way to add an emoji in the title, and not change the URL, since in this forum https://meta.discourse.org/ , if you add an emoji in the title, after the post has been created, the URL doesnโt change.
In my install, if I add an emoji to the title, after the post has been created, the URL does changes.
Youโre right, I just saw your second post. I will leave this to someone more knowledgeable to answer 
Itโs different if you add the emoji as :) or if you add it as :slightly_smiling_face:.
First isnโt added to the URL, while the second will be.
Both URLs will work, and we have a canonical pointing to the, well, canonical URL.
Thanks. Anyway, I think I found an easy solution to my need. I hope this helps someone else:
1- Go to a page containing an unicode list of emojis, like https://emojipedia.org or http://xahlee.info/comp/unicode_emoticons.html
2- Copy your emoji and paste it in the title ๐ท ๐ ๐
๐ท.
It will still appear in the title but not in the url. You can use many emojis ๐ท ๐ ๐
๐ท 
, and not only the basic ones, like :) :(
Note: in the editor and in the preview, they are showing if firefox, but not in chrome browser at least in my computer
@codinghorror this is a bit of a strange inconsistency here, I donโt really mind it that much but you can work around emojis sneaking into slug now by having actual emojis in the title vs :smile: and such.
We need to stop doing this because it hurts non English sites a lot, as previously discussed.
Should we strip emoji from slug unconditionally or just for non-English sites, @techAPJ worked on this last so he can do whatever you think is right here.
For parity with other languages I think we have to strip emoji strings from URLs / titles @techapj โ otherwise it is a giant can of :bug:s to untangle that 
The other option is to keep unicode emoji in URLs but do we really want to go there?

Okay, weโll now strip emoji strings from slug / URL.
