[boost] [algorithm] non-ascii characters in boyer_moore.hpp

Hi Marshall, `boost/algorithm/searching/boyer_moore.hpp` contains a non-ascii character ("–", en dash) at line 37: 36: Explanations: boostinspect:noascii (test tool complains) 37: http://en.wikipedia.org/wiki/Boyer–Moore_string_search_algorithm Would it be better to URL-encode the dash as "%E2%80%93" rather than relying on `boostinspect:noascii`?
