This section describes functionality and concerns related to pre-1.5.50 releases of OpenAFS for Windows. This release stores all file names on the file servers as Unicode encoded using UTF-8.
OpenAFS for Windows implements an SMB server which is used as a gateway to the AFS filesystem. Because of limitations of the SMB implementation in pre-1.5.50 releases, Windows stored all files into AFS using OEM code pages such as CP437 (United States) or CP850 (Western Europe). These code pages are incompatible with the ISO Latin-1 or Unicode (UTF-8) character sets typically used as the default on UNIX systems in both the United States and Western Europe. Filenames stored by OpenAFS for Windows were therefore unreadable on UNIX systems if they include any of the following characters:

The pre-1.5.50 OpenAFS Client provided an optional registry value, StoreAnsiFilenames, that could be set to instruct OpenAFS to store filenames using the ANSI Code Page instead of the OEM Code Page. The ANSI Code Page is a compatible superset of Latin-1. This setting is not the default setting because making this change would prevent OpenAFS for Windows from being able to access filenames containing the above characters which were created without this setting.
All versions of OpenAFS for Windows 1.5.50 and above exchange file names with Microsoft Windows using the Unicode character set. All file names are read from and stored to AFS file servers using the UTF-8 encoding of Unicode. As a result the StoreAnsiFilenames option is no longer supported.
