Add-On Type(s)



Converts user's input into unicode's normalization form C.

In many languages some characters can be used together with one or more diacritics.
In unicode a character having diacritics can be represented either by one symbol or by sequence of several symbols consisting of the main character and one or more combining diacritical marks.

Support of combining diacritics vary widely among OSes and fonts. In many cases combining diacritics are placed wrongly and cause the text to look ugly. To avoid this in all cases when it is possible characters having diacritics should be represented by single symbols.

Site admins have no control over what symbols will be entered by the users, many of whom do not know anything about unicode and the possible ways of representing characters having diacritics; users just type or copy/paste the text.

Unicode Normalizer extension will convert all user input (i.e. weblog entries, comments and forum posts) when they are submitted into unicode’s normalization form C in which characters having diacritics are represented by single symbols.

REQUIREMENTS: This extension requires either PHP version 5.3 or higher, or PHP extension PECL intl.
