Angus,

Have you tried the Boost.Filesystem "i18n" branch from CVS?

In a week I'm due to present a proposal to the Library Working Group to add 
what is essentially Boost.Filesystem i18n to TR2. See 
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1841.html

Assuming the reaction is favorable, the plan is to move the i18n branch to 
the CVS HEAD. Thus while I'm quite interested in your suggestions, I'd like 
to see if they apply to the i18n code rather than the 1.33 code, which is 
essentially legacy code at this point.

Thanks,
