This also affects vertical bars ( | ) as seen at ttps://en.wikipedia.org/w/index.php?title=Paper_Planes&diff=585505452&oldid=581736416
Another diff, this time involving a {{nowrap}} template: https://en.wikipedia.org/w/index.php?title=Michael_Jackson&curid=14995351&diff=595247974&oldid=595208734
This only seems to affect nbsp's that are present in ref names (where they probably oughtn't be anyway).
According to https://en.wikipedia.org/w/index.php?title=Colours_in_the_Dark_%28album%29&curid=39317223&diff=595492480&oldid=593715294 it appears that this happens on HTML codes for things other than non-breaking spaces. #124 is a vertical bar.
Other example on frwiki https://fr.wikipedia.org/w/index.php?title=Salon_international_de_l%27agriculture&curid=205829&diff=101773303&oldid=101729054
Apparently, the user didn't even modify the chapter where the problem occurs.
Here's another:
This time, the ref name contained a template: <ref name="{{BillboardURLbyName|artist=the national|chart=Billboard 200}}">
Like most of the others, this is probably the result of a sloppy script.
I can't reproduce this in Chrome, Safari, Opera or Firefox. Is it possible that this is a browser plug-in or a very odd browser corruption?
It happened yesterday:

I'll ask the user who encountered this one:
since she's pretty active.
No steps to reproduce; no-one managed to reproduce; no new known occurrences for nearly a year. Setting status to STALLED.
The reply of that user was "I am using Mozilla Firefox on a Dell Inspiron One desktop computer."
