System.String.IsNormalized Method

Indicates whether this string is in Unicode normalization form C.


public bool IsNormalized ()


true if this string is in normalization form C; otherwise, false.


Some Unicode characters have multiple equivalent binary representations consisting of sets of combining and/or composite Unicode characters. The existence of multiple representations for a single character complicates searching, sorting, matching, and other operations.

The Unicode standard defines a process called normalization that returns one binary representation when given any of the equivalent binary representations of a character. Normalization can be performed with several algorithms, called normalization forms, that obey different rules. The .NET Framework currently supports normalization forms C, D, KC, and KD.

For a description of supported Unicode normalization forms, see System.Text.NormalizationForm.
