Ha, I used DeepL for translating to French once and it translated "best regards" to something like "I hope the president of the EU will find this all in accordance" or something similar to that. I presume it was because most European language models were trained on UN and EU documents that are made available in tons of languages.

I've learned to throw the output of any machine translated text into a reverse machine translator and see if the text still makes sense. For non-European languages, I just assume the translated text is flawed but will hopefully get the message across well enough.
