Docs For Class I18N_UnicodeNormalizer

[line 74]
Unicode data compiler

Compiles the data files to files with Unicode code points converted to UTF-8 characters, e.g. utf8/CanonicalCombining.php. Compiles the data files to files with the Unicode code points converted to their UCN format, e.g. ucn/CanonicalCombining.php. The latter is useful for testing purposes.

The original Unicode.org data files are split into quick check files, a character combining file, decomposition files, a composition exclusion file, character composition files, test files. Each file contains a PHP array with the characters as key.

The Hangul data is generated with an algorithm.

The compilation only needs to be run once.

__construct (Constructor) [line 162]

void __construct(
[string
$dir = ''], [string
$codeFormat = ''], [boolean
$forceCompile = false], [integer
$limitedDataSet = false])

The class constructor

Sets the Unicode code point format, the force-compilation option, the code points range limit. Sets the paths of the data and compiled file names

Access: public

Parameters:

string	`$dir`	—	the data/compiled files base directory, the default is set by the normalizer
string	`$codeFormat`	—	'utf8': for production, or 'ucn': for testing purposes, the default is 'utf8'
boolean	`$forceCompile`	—	compilation option: files are to be (re)compiled if true, files are recompiled as needed if false
integer	`$limitedDataSet`	—	compiles a small subset of data for testing/coverage purposes if true, or use all data otherwise
