| | #REDIRECT [[Class: I2CE_Hyphen (4.1.7)]] |
| It is contained in the module [[iHRIS Module List#textlayout|textlayout]] in the package [https://launchpad.net/textlayout TextLayout Tools]
| |
| | |
| The class is defined in the file: [http://bazaar.launchpad.net/~intrahealth+informatics/textlayout/4.0.0-release/files/head:/lib/I2CE_Hyphen.php lib/I2CE_Hyphen.php]

| | |
| PHP script implement Knuth's and Liang's hyphenation algorithm
| |
| | |
| as described in http://lingucomponent.openoffice.org/hyphenator.html
| |
| | |
| In particular it uses the 'mashed up' dictionary files
| |
| | |
| | |
| | |
| Note: Internally, by default, all strings are encoded as UTF-8.
| |
| | |
| This is highly recommended to enable the unicode preg to work
| |
| | |
| quickly (without having to covert to UTF=8 and then back).
| |
| | |
| | |
| | |
| Note: Does not (yet) support the non-standard hyphenation of hungarian,
| |
| | |
| swedish, etc.
