So it seems that information in these documents and that will be "used" are
already authorized for redistribution. But they cannot be altered and the
copyright notice must be kept.
Your question is good, because there's normally a required authorization
licence, even to create derivative files that would "use" the information
listed there. Of course, if the software is developped with a Microsoft
development tool, the licence of that development tool will allow
distributing an application that use these charsets.
The problem is then: can we use and map the Microsoft charsets on non
Microsoft development platforms or in softwares not built with Microsoft
development tools in which these mappings are implicitly used, as part of
the MSDOS or Windows systems? For "OEM" codepages, it seems that Microsoft
has inherited and used charsets initially created by IBM, but it may have
licenced it from IBM to create MSDOS. The situation is much less clear for
Microsoft ANSI codepages.
I hope that when Microsoft offered to Unicode these files to be published by
Unicode, it has signed the licence agreement that authorizes such
publication by Unicode. It would be hard if Microsoft wanted later to claim
royaltees for all unauthorized use of these charsets (i.e. the mapping
between Windows ANSI codepages and Unicode, which, in the current form,
constitutes a derived work based on copyrighted product, i.e. the Microsoft
