When bookmarking a URL like:
You get this bookmark title:
YouCare - The charitable search engine – Get this Extension for 🦊 Firefox
Then, if you copy and paste that URL title into Notepad++, the non-ASCII Unicode character (a fox, in this example), gets displayed as a box (a rectangle, to be specific).
How do you configure Notepad++ to show non-ASCII Unicode characters like this?
Note: This questions is related, but different than Notepad++ special Unicode characters not displaying properly
That question deals with what is likely a bug in Notepad++ that causes the characters to be displayed differently after the file is saved and reopened. This question deals with characters that do not even appear correctly when pasted into Notepad++.
I tried saving the above title string as a text file in Notepad++ and then reopened it. No change. I then tried copying the text from Notepad++ into StackExchange (in Firefox), and the text displays correctly in Firefox.
That means Notepad++ is storing the character correctly, but not displaying it as desired.
Using a hex editor, I see the fox character is being encoded as:
F0 9F A6 8A, which is as it should be: https://www.unicode-search.net/unicode-namesearch.pl?term=fox%20face
