Question

我創造了從丹麥網站的RSS閱讀器，他們有一些像這樣的事情在他們的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> 

請幫助我解碼丹麥文本 - 由於mod oversover＆oslash; mmelse - 在unicode中的NSString Bl å vand。
