Created attachment 52399 [details] encoding code point to unicode mapping table of code page 708
This is to be best of my knowledge the mapping table of code page 708. It is derived from hexdump'ing c_708.nls from the typical windows installation and some on-line description about what the format of the nls file type might be.
Unfortunately I don't think that Wine can use this (and attaching such dump may violate a copyright), there is a reason why Wine uses unicode.org tables.
