Infinite recursion in the tokeniser when showing warnings #99891
Description
Turns out that showing warnings in the tokenizer is quite tricky because in the process of showing the warning we need to fetch the encoding which needs to tokenize the first two lines and if the warning is there that leads to an infinite loop. Check for instance with a file contaning:
0b1and x
Notice that this only happens when tokenizing files.
