# This regex validates that there is no substring: b'
# The reason why we want to validate that is that we want to
# make sure that stderr is actually decoded so that in
# exceptional cases the error is properly formatted.
# As for how the regex works:
# `(?!b').` is a negative lookahead, meaning that it will only
# match if it is not followed by the pattern `b'`. Since it is
# followed by a `.` it will match any character not followed by
# that pattern. `((?!hede).)*` does that zero or more times. The
# final pattern adds `^` and `$` to anchor the beginning and end
# of the string so we can know the whole string is consumed.
# Finally `(?s)` at the beginning makes dots match newlines so
# we can handle a multi-line string.
