Description:

"...Unicode's normalization is the concept of character composition
and decomposition.

Character composition is the process of combining simpler characters
into fewer precomposed characters, such as the n character and the
combining ~ character into the single n+~ character. Decomposition is
the opposite process, breaking precomposed characters back into their
component pieces...

...Normalization is important when comparing text strings for
searching and sorting (collation)..." [Wikipedia]

Performs the 4 normalizations:

NFD: Canonical Decomposition NFC: Canonical Decomposition, followed by
Canonical Composition NFKD: Compatibility Decomposition NFKC:
Compatibility Decomposition, followed by Canonical Composition

Complies with the official Unicode.org regression test.

Uses UTF8 binary strings natively but can normalize a string in any
UTF format.

Fully tested with phpUnit. Code coverage test close to 100%.

In PEAR status of this package is: stable.
