Я создал rss-ридер для сайта из Дании, у них есть кое-что подобное в их CDATA: 

<description><![CDATA[><p><img src="http://www.fotoagent.dk//single_picture/10851/1/small/18.Sep.2008_033_fodring_v_h_fde_40.jpg" alt="" width="150" /></p><p>For at sikre Bl&aring;vand by mod oversv&oslash;mmelse, er Kystdirektoratets strategi, at fastholde kysten mellem h&oslash;fde 1 og 6 ved at foretage strandfodringer med sand.<br /><br />Efter udbud har Rohde Nielsen A/S vundet entreprisen med at strandfodre ved Bl&aring;vand i 2010. <br /><br /><br />Der vil blive fodret med 110.</p>]]></description>

Пожалуйста, помогите мне расшифровать датский текст - для сикре Bl & v; vand by mod oversv & oslash; mmelse - для NSString в юникоде.
