Beman.github.com/string-interoperability/interop_white_paper.html describes Boost components intended to ease string interoperability in general and Unicode string interoperability in particular. These proposals are the Boost version of the TR2 proposals made in N3336, Adapting Standard Library Strings and I/O to a Unicode World. See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3336.html. I'm very interested in hearing comments about either the Boost or the TR2 proposal. Are these useful additions? Is there a better way to achieve the same easy interoperability goals? Where is the best home for the Boost proposals? A separate library? Part of some existing library? Are these proposals orthogonal to the need for deeper Unicode functionality, such as Mathias Gaunard's Unicode components? --Beman
