Function msGetUnicodeEntity

mapstring.c:1968–2039

* this function tests if the string pointed by inptr represents * an HTML entity, in decimal form ( e.g. Å), in hexadecimal * form ( e.g. 水 ), or from html 4.0 spec ( e.g. é ) * - returns returns 0 if the string doesn't represent such an entity. * - if the string does start with such entity,it returns the number of * bytes occupied by said entity, and stores the unicode

 * bytes occupied by said entity, and stores the unicode value in *unicode
