Text normalization is the process of transforming text into a single canonical form that it might not have had before. Normalizing text before storing or processing it allows for separation of concerns, since input is guaranteed to be consistent before operations are performed on it. Text normalization requires being aware of what type of text ...
The standard also defines a text normalization procedure, called Unicode normalization, that replaces equivalent sequences of characters so that any two texts that are equivalent will be reduced to the same sequence of code points, called the normalization form or normal form of the original text.
Unicode recommends authors use the plain text compatibility decomposition equivalents instead and complement those characters with rich text markup. This approach is much more flexible and open-ended than using the finite set of circled or enclosed alphanumerics to give just one example.
To deal with this, Unicode provides the mechanism of canonical equivalence. In this context, canonicalization is Unicode normalization. Variable-width encodings in the Unicode standard, in particular UTF-8, may cause an additional need for canonicalization in some situations.

ICU provides the following services: Unicode text handling, full character properties, and character set conversions; Unicode regular expressions; full Unicode sets; character, word, and line boundaries; language-sensitive collation and searching; normalization, upper and lowercase conversion, and script transliterations; comprehensive locale ...
In computing, uconv is a command-line tool that is bundled with International Components for Unicode that converts text files between different character encodings.It is very similar to the iconv command that is part of the Single UNIX Specification which is usually implemented using libiconv.
