| 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.
