Re: is there any way to change already defined character codes?

Are you basically wanting the ordering to be different?

Unicode does not have any expressed or implied warranty that the ordering of
characters will be anything like what a user would expect (how can it, when
even so many languages that use the same scripts have entirely different,
occasionally conflicting, collation rules?

It is up to the software to make the necessary collation rules happen.

For example, in Windows 2000 there are two different sorts supported for
Georgian: "modern" and "traditional." The difference is that modern has four
letters (He, Hie, We, and Har, both Capital and Small) sort at the end of
the alphabet (which I presume corresponds to the sort that you do not
like?), while the traditional sort has:

* He appearing between Zen and Tan
* Hie appearing between Nar and On
* We appearing between Un and Phar
* Har appearing between Xan and Jhan

I presume the above "exceptions" more closely match the sort you would
expect? And if there are more, this would be very valuable information (as
the rules behind all new "sorts" like this are that a valid need to sort
text differently was identified.

As a rule, Unicode order is not intended to be nor does it explicitly decide
to follow any kind of collation rules for code point order.

FWIW, the LCIDs behind these two sorts under Windows 2000 (used in the C
CompareString and the VB StrComp) are:

Traditional: 1079 (0x0437)
Modern: 66615 (0x10437)
