You could literally replace that emoji with the well known phrase "wink, wink." It is well understood and avoids the ambiguity of emoji.

But then you look like an idiot, which is the opposite of the purpose.

I can scarcely imagine a faster way to look socially inept in text, than writing out so explicitly what are supposed to be nuanced and subtle actions. Eye roll.

I'm not a native English speaker, but I associate the phrase "wink, wink" with lechery more than with flirting.

That said, I also don't usually associate the wink emoji with flirting, but more with tongue-in-cheek fun. Context matters I guess.

There are places beyond the English-speaking world. As far as I know, there's no equivalent to "wink, wink" in my native language.
