The thing is if both uses the same strategy (dfa) why one works and the other don't ?
I mean regular expressions work but flex doesn't with both regexes.

With this \"(?:\\.|[^\"\n\r])*\"|'(?:\\.|[^'\n\r])*' and this \"(?:\\.|[^\"\n\r\\])*\"|'(?:\\.|[^'\n\r\\])*' regex on https://regex101.com/ the following languages recognize all strings: Java8, Golang, Python, Javascript and PCRE .

Those other implementations aren't using DFA/leftmost longest.
There are actually multiple regex flavours, but let's keep things simple.
