Any that supports <<, >>, and |, and wants to do Latin-1.  In
French-speaking regions, « and » are more likely to be quoting
metacharacters than redirection metacharacters, but still
metacharacters.

Not that it really matters much - the point of "ensure that anything
not specifically thought about is unsafe" is as valid - or invalid - as
ever regardless of the details of the example.
