What is Code Page 951 (CP951)?
Most Chinese Windows users should have heard about CP950, which is the implementation of Big5 character mapping inside traditional Chinese Windows. However, what the heck is CP951? Is it somehow related to CP950? Yes! This code page exists, but is rarely mentioned in internet, and I didn’t manage to find any page that clearly documents it so far; not even inside M$’s web site.
Now most of the content is moved to another static page, since it deserves some research value. Visit that page for more detail.
If you install the HKSCS package, it replaces the original CP 950 on the machine with the 951 version, which is why it says 950 internally.
