Re: [Boost-users] Boost's direction regarding UTF8 -> UTF32 and UTF32-> UTF8

What is the consensus on best-practice regarding the conversion of UTFx to/from UTFy?

Consensus? Hardly any yet I'm afraid.

I see that Boost Regex uses ICU for some conversions, but is there any user exported interface for conversions?

Actually regex doesn't need ICU for that - it uses the iterators in boost/regex/pending/unicode_iterator.hpp most of the available conversions are supported there I think. HTH, John.
