Kind of. It depends on whether the tool extracts copyrightable elements from 
the source.

Either way, if we go with the strict interpretation and decide that

{0x0028, 0x0029, bidi_bracket_type::open},
{0x0029, 0x0028, bidi_bracket_type::close},
{0x005B, 0x005D, bidi_bracket_type::open},
{0x005D, 0x005B, bidi_bracket_type::close},
{0x007B, 0x007D, bidi_bracket_type::open},
{0x007D, 0x007B, bidi_bracket_type::close},

is a derived work of a Unicode data file, I see no way of ever having a 
Unicode library in Boost.
