Unfortunately yes. We use boost::filesystem in our AV engine which is still used by many Windows 9x clients, including several Windows 95!
Given the interface standardization, we will use boost::filesystem in 9x anyway, either by keeping v2 or even if you decide not to support 9x in v3 by adding to it what is needed.
What I mean is that we will devote resources anyway to this task.

You are right of course, no magical encodings are possible. It will suffice if ANSI Windows APIs are called in this build instead of wide ones.
This is the problem introduced in v3: the narrow API versions are never used.

Please don't hesitate to ask what you need. If you preder so you may contact me directly.
