Mapnik fails to build with Boost 1.83 about mapnik

[artemp]

@SMillerDev - unicode_iterators are still there but boost_1_83 re-arranged include directives e.g

grep -rn 'utf8_output_iterator' ../boost_1_83_0/boost
../boost_1_83_0/boost/regex/v5/icu.hpp:1199:inline utf8_output_iterator<OutputIterator> make_utf32_out(OutputIterator o, std::integral_constant<int, 1> const*)
../boost_1_83_0/boost/regex/v5/icu.hpp:1250:inline BaseIterator extract_output_base(const utf8_output_iterator<BaseIterator>& b)
../boost_1_83_0/boost/regex/v5/unicode_iterator.hpp:50:class utf8_output_iterator;
../boost_1_83_0/boost/regex/v5/unicode_iterator.hpp:790:class utf8_output_iterator

...

I can't replicate on macOS 13, please provide more details about you build environment.

As a solution try adding #include <boost/regex/icu.hpp> in generic_json.hpp and report back if this fixes compile error.

Oh, probably good to note for this issue that I'm building the latest release of Mapnik.

The pull request #4413 should resolve this issue.
