Indeed the '?' meta-char is not portable in "sed".
While almost every Unix-based RE parser I've ever seen have always
supported the '?' meta-char, the REs handled by 'ed' and 'sed' have
often been limited subsets. On V7 '?' works in grep but not ed or sed.
However what's the context for this question?
