Is there a "you know" in non English languages?

[CZroe]

The interjection "you know". You probably know what that is without me giving any examples in a sentence. But it shows up almost everywhere on tv, the net and out in public. Like news reporters saying "The valuation of this stock is, you know, going up and up." Or hearing people anywhere saying "that restaurant has the best, you know, overall menu." And on and on. The phrase or interjection annoys me a lot. But anyway on with the topic.

So I tried a Google search if other languages have a you know. And I couldn't really find an answer for the "you know" I'm asking about. Ticks me off, I ask a simple question on Google and can't get an answer. Which means I probably phrased the search entry incorrectly or used the wrong search engine. So I'm here. Is there a "you know" in other languages? I wondered if "tu sabes" (you know) would be it in Spanish but apparently not. Spanish has tu sabes but it's used more formally like "do you know how many people live in this city?"

"You know" is short for "you know what I'm saying," which is exactly what French people mean when they say "je na sais quoi." It's literally "how do you say?" but they obviously expect you to understand what they are trying to say in order to answer that.

It has a certain, you know... flare.

It has a certain, je ne sais quoi... flare.
