ustring::compose and win32

[Bastien Durel <bastien durel org>]

Hello,

I'm trying to port an application under win32, but I got a problem with
ustring::compose.
When I try to use an int as a parameter, compose throws an exception
(ConvertError) saying it cannot convert from wchar_t to utf-8.

is there a workaround ?

Thanks,
