Aitor writes this about a remarkable similarity between the FreeDOS NLS and Microsoft's NLS for DOS. This just demonstrates that the same engineering problem is often solved by two independent observers in the same fashion:
I have discovered that Microsoft do also have NLS tables. They are here: http://www.microsoft.com/globaldev/nlsweb/ and have all the information.
The fact is, it is SO impressive (at least for me!!) HOW similar are to my own tables, using a similar layout, similar fileds, also tokens for date/time. Compare with http://inicia.es/de/aitorsm/FreeDOS/NLStbl/NLS-en.htm.
Ok, at least there's a source for most of the information...
