vfs_catia - translate illegal characters in Catia filenames

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed
       by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.

       New version written by Guenter Kukkukk kukks@samba.org

Samba 4.22.3-Ubuntu-4.22.3+dfs                     07/21/2025                                       VFS_CATIA(8)

       Character mapping must work in BOTH directions (server -> client and client -> server) to get unique and
       existing file names!

       A NOT working example:

                   [CAD]path=/data/cadvfsobjects=catiacatia:mappings=0x3a:0x5f

       Here the colon ":" is mapped to the underscore "_".

       Assuming a server-side filename "a:should_work", which is translated to "a_should_work" for the client.

       BUT the reverse mapping from client "a_should_work" to server will result in "a:should:work" - something
       like "file not found" will be returned.

       This VFS module is part of the samba(7) suite.

       The Catia CAD package commonly creates filenames that use characters that are illegal in CIFS filenames.
       The vfs_catia VFS module implements a character mapping so that these files can be shared with CIFS
       clients.

       This module is stackable.

       The parameter "catia:mappings" specifies the mapping on a per-character basis, see below.

       Map server-side quotation-marks (") to client-side diaeresis (¨) on filenames in the [CAD] share:

                   [CAD]path=/data/cadvfsobjects=catiacatia:mappings=0x22:0xa8

       Perform comprehensive mapping of common Catia filename characters:

                   [CAD]path=/data/cadvfsobjects=catiacatia:mappings=0x22:0xa8,0x2a:0xa4,0x2f:0xf8,0x3a:0xf7,0x3c:0xab,0x3e:0xbb,0x3f:0xbf,0x5c:0xff,0x7c:0xa6

       Server-side filename to be translated (Note that the path delimiter "/" is not used here):

       a\a:a*a?a"a<a>a|a

       Resulting filename, as seen by the client:

       aÿa÷a¤a¿a¨a«a»a¦a

       vfs_catia - translate illegal characters in Catia filenames

       catia:mappings = SERVER_HEX_CHAR:CLIENT_HEX_CHAR
           SERVER_HEX_CHAR specifies a 0x prefixed hexedecimal character code that, when included in a Samba
           server-side filename, will be mapped to CLIENT_HEX_CHAR for the CIFS client.

           The same mapping occurs in the opposite direction. Multiple character mappings are separated by a
           comma.
