[TCLCORE] TIP 726

[Harald O. <har...@el...>]

Ashok,
thanks for authoring TIP 726, this is welcomed !

The covered normalization functions are:
D118 Normalization Form D (NFD): The Canonical Decomposition of a coded 
character sequence.
D119 Normalization Form KD (NFKD): The Compatibility Decomposition of a 
coded character sequence.
D120 Normalization Form C (NFC): The Canonical Composition of the 
Canonical Decomposition of a coded character sequence.
D121 Normalization Form KC (NFKC): The Canonical Composition of the 
Compatibility Decomposition of a coded character sequence.

So, two are decompositions, two are compositions.
The first two basically decompose a Unicode to multiple others, the 2nd 
two compose multiple Unicodes to one (simply speaking) (it is much much 
more difficult).

I would name them in a more verbose way, like decompose and compose.

The "NF" meanes "Normalizes form". D/C is for decompose or compose and K 
is for compatibility.

Thanks for all,
Harald
