Samy, it's computer language, it is not decipherable, it's a series of symbols, nothing more. I put it through my keyboard symbols and more than half did not come up as recognizable computer interaction!
With the current flow of information through the Airbnb platform this situation of 'double speak' is going to arise. There is every probability that a reservation will arrive shortly in a language that you will understand if it is a genuine reservation request.....if it doesn't, report it to Airbnb and let them deal with it.
In your Airbnb account settings you would have specified a language you wished you communications to arrive in. Anything outside that should not be regarded as irrelevant.
Give CX a call if you are concerned!
