 * cc-tool -> already depends on wchar
 * gnuradio -> already depends on wchar
 * kodi -> already depends on wchar
 * libftdi1 -> does not depend on wchar yet, but only the C++ bindings
   of libftdi1 need boost, so I think it's OK
 * mpd -> already depends on wchar
 * pulseview -> already depends on wchar
 * python-libconfig -> already depends on wchar since it depends on
   python or python3, and both depend on wchar
 * thrift -> already depends on wchar
 * yaml-cpp -> would add a wchar dependency
 * zmpqq -> already depends on wchar

So the only affected packages are the C++ bindings of libftdi1 and
yaml-cpp.

Conclusion: I believe it's reasonable to add a wchar dependency
globally to boost. It's a pain to keep track which sub-option of boost
needs or does not need wchar, and boost is a "big" thing, so having an
additional toolchain dependency that is nevertheless already very
common, is not a big issue.

Thanks!
