An IP user on the English Wikipedia reports the following slightly alarming
bug:

"After I edited text near a link, "♙♙♙♙♙♙♙" characters started appearing
around
once a second, and I couldn't stop them or delete them."

Based on another bug report left a few minutes later by the same user they
were
using MobileSafari on iPad 2 with iOS 6.1.3

I can't replicate this in Firefox on a Linux PC and don't have an iPad to
test
on.

Since you asked,in VE test edit we had encountered it at mr wiki http://mr.wikipedia.org/w/index.php?title=तेकिर्दा_प्रांत&diff=prev&oldid=1189390 When I increased space.I suppose developers already may be taking care of this.

I suppose en wiki maya be needs to track nowikis with better targeted edit filters for space and other mark up aspects.Thats my guess.
