Wondering if there's a fast/efficient built-in way to determine

CR, LF, or Tab?
I know I can look at the chars of a string individually and
compare them against a set of legal chars using standard Python
code (and this works fine), but I will be working with some very
large files in the 100's Gb to several Tb size range so I'd
thought I'd check to see if there was a built-in in C that might
handle this type of check more efficiently.
Does this sound like a use case for cython or pypy?
Thanks,

How about doing a .replace() method call, with all those characters
turning into '', and then see if there's anything left?
