E201: not detected for tab instead of space

[spaceone]

printf 'foo(\tbar)\n' | pep8 -
→ nothing detected

while
printf 'foo( bar)\n' | pep8 -
detects stdin:1:5: E201 whitespace after '('

Is there actually a tab inserted in the first example? Or is it that you are printing at \t symbol?

The way you have it written is not a bug...

This is the linux command printf. So \t will produce a tab, yes!

Still broken with pycodestyle 2.7.0
