Class Normalizer
Utility for the normalization of Unicode Strings to NFC form.
This class tries to use the java.text.Normalizer class in JDK 1.6 first and, if it the class is not found (Java version invalid input: '<' 6), then it will use the ICU4J com.ibm.icu.text.Normalizer class (in this case, a ClassNotFoundException will be thrown if ICU4J is not present).

normalizeToNfc
Normalize Unicode-input message to NFC.
This algorithm will first try to normalize the input's UNICODE using icu4j's com.ibm.icu.text.Normalizer and, if it is not present at the classpath, will try to use java.text.Normalizer. If this is not present either (this class appeared in JavaSE 6), it will raise an exception.
- Parameters:
message
- the message to be normalized- Returns:
- the result of the normalization operation
-
normalizeToNfc
public static char[] normalizeToNfc(char[] message) Normalize Unicode-input message to NFC.

- Parameters:
message
- the message to be normalized- Returns:
