Each U+002D HYPHEN-MINUS in [0-9A-Za-z_-/.\] is treated as a member of a range. The third one, which appears to have been intended to be a literal, is part of an empty range because the starting point U+005F LOW LINE is greater than the endpoint U+002F SOLIDUS, resulting in at least some grep implementations not considering U+002D, U+002F or U+005F to match the pattern. This resulted in one of the dbus-launch tests being unintentionally skipped when it used a regex based on the one in the spec. regex(7) suggests "To include a literal '-' [in a bracketed character set], make it the first or last character".
