I didn't do anything, and when I clicked to translate :en:Nebojša Tower to Hebrew, it showed me some strange symbols (if you wanna know: it was with the google translate option; the symbols are before the ref). By the way, it's not the first time.

@Euro know, do you remember the last action before the system showed you two emoji-Snowman? As linked by @Arlo Barnes, my case is very similar. Thank you for your input either here or at the link. Cheers, Omotecho
@Omotecho Nothing special; Only clicked on it (It's no matter if you change something in another paragraph, it's still will be shown).
By the way, it was also in one of the last few translations of mk-he pair (I don't remember the exact one).
Thank you, @Euro know, for your reply. So I find similarity that in my case, I only deleted one double byte character, then the error happened. Hope more cases will be reported so that we will have more cases to compare. Again, you are kind to reply, thank you. Cheers,
