How bizarre can the Quantum two slit experiment get? Note 1: Don't apprehend my question as 'quantum woo'. I do not mean so and  hate anyone who does.
Note 2: I am just a 14 year old physics enthusiast. Don't expect any background.

On to the real question. I recently read about the Quantum two slit experiment and learnt about how the particles go through both slits at the same time (thanks Feynman) unless I actually measure the 'which path' (which slit) information. If i do, the interference pattern disappears.

Lets say i have the experiment setup. I have sensitive sensors which detect which path the particle took. The data goes to a computer which processes the data and shows me the data.

Now lets take the following cases:
1)The computer has an inherent flaw. Sometimes, it shows the wrong which path value. That way, i know the which path data, but its wrong. So the interference pattern shouldn't disappear. 

2)The computer is set in a different language. Instead of 'path one' or 'path two', it says 'útvonal egy' or 'útvonal két' (hungarian), which i don't know. So i know the which path data, but can't understand it. So the interference pattern shouldn't disappear.(again)


3)Same as above, but i use Google Translate. So immediately after I'm done using it, should the interference pattern immediately disappear?


In the above three cases were my understandings correct? If so, Quantum bizarrenes has no limit :)
 A: Your flaw lies in that you think "which path information" means that your consciousness is it that collapses the wavefunction, which in fact was the interpretation Wigner and friends (note the pun) had for quantum mechanics. But this interpretation is regarded as incorrect. In your case we could even perform the experiment and we would note that the interference pattern would already have disappeared in all your 3 cases.
What really matters is when the measurement occurs, not when you read off what you measured. I.e. you send a photon or something to tell you which slit it has gone through. That is what makes the pattern disappear. What you do after is just you messing with the photon. (i.e. google translator etc. doent matter)
A: Pop-science explanations of the two-slit experiment often confuse "a person knowing" with "an instrument detecting". But it's the latter that matters, not the former.
The interaction with a detector is what makes the interference pattern go away. Whether or not the detector then reports the result to you, and how it does so, has no relevant effect on the particle's path.
The reason interaction with the detector matters is interference only happens when every detail ends up the same. The detector's state is a detail that doesn't end up the same, so it prevents the particle-went-left paths from interfering with the particle-went-right paths.
(If you are able to erase the detector's state somehow, then the paths can interfere again. You can even delay the erasure until later, but you'll need some clever measurements and after-the-fact grouping to recover the hidden interference patterns. Also in these cases the term "detector" starts to be misleading, since we're actually talking about manipulating coherent quantum information.)
A: There is often a misunderstanding about what observation means. Observation is not necessarily a human activity, it is an interaction with the experiment. Whether you do understand the language is irrelevant, there has been a physical interaction, and this is what counts.
