Zero width character in the URL of the pictures

[angoca]

When resolving the notes created from StreetComplete, and these notes includes a photo, the URL of the photo includes a zero width character, just before the p, after the first slash. I am resolving a lot of notes from JOSM, and the URL has a zero width that creates some issues when viewing in the browser or copying the URL.

This is the original URL from the note:

https://westnordost.de/​p/65715.jpg

When copy/pasting in the browser, it is converted into:

https://westnordost.de/%E2%80%8Bp/65715.jpg

The character is this e2 80 8b which is the 200+B in UNICODE.

I do not know why the application is adding this "invisible" character in the notes, but this is creating problems to see the picture.

One example of this kind of error could be seen at: https://www.openstreetmap.org/note/2900036 when editing from JOSM, and copy pasting the URL.

It looks like there is something wrong with your browser. The URL in the HTML does not contain this unicode character. I can tap on it no problem and https://westnordost.de/p/65715.jpg (a church) will be displayed:

It also look OK in OSM notes dump, so StreetComplete is likely not the problem here:

That being said, I've also seen that behavior lately in JOSM (testing 18193), but haven't had time yes to find what exactly causes the problem (I've upgraded underlying Debian and its Java too, as well as a JOSM and StreetComplete).

Interestingly problem for me seem to occur only when JOSM is started via webstart link in browser - and in those cases I cannot open link directly by clicking on it, but only by copy/pasting (after triple-clicking the link), which is when the bug manifests. If I start the JOSM from shell with java -jar josm-tested.jar direct clicking works. If I file the bug elsewhere, I'll link here just in case someone else stumbles upon it (or if someone else is faster, please go ahead, I'm somewhat swamped at the moment)
