I'm uneasy about contrib/gen_wcwidth.cpp doing the generation using host libc's wcwidth. The effect is that libcpp/generated_cpp_wcwidth.h is *not* reproducible unless you know exactly what host (libc version, locale used when running the program, distribution patches to libc and locale data) was used to run the program. I think we need a generator that works from Unicode data in some way so we can explicitly say what version of the (unmodified) Unicode data was used. -- Joseph S. Myers jos...@codesourcery.com
