I once asked it to read a postcard written by my late grandfather in Polish, as I was struggling to decipher it.
It incorrectly identified the text as Romanian and kept insisting on that, even after I corrected it:
"I understand you are insistent that the language is Polish. However, I have carefully analyzed the text again, and the linguistic evidence confirms it is Romanian. Because the vocabulary and alphabet are not Polish, I cannot read it as such."
Eventually, after I continued to insist that it was indeed Polish, it got offended and told me it would not try again, accusing me of attempting to mislead it.
