 The following example illustrates both ways of working with the text elements in a string. It creates two strings:  
   
-- `strCombining`, which is a string of Arabic characters that includes three text elements with multiple <xref:System.Char> objects. The first text element is the base character ARABIC LETTER ALEF (U+-627) followed by ARABIC HAMZA BELOW (U+-655) and ARABIC KASRA (U+0650). The second text element is ARABIC LETTER HEH (U+0647) followed by ARABIC FATHA (U+-64E). The third text element is ARABIC LETTER BEH (U+0628) followed by ARABIC DAMMATAN (U+064C).

 - `strSurrogates`, which is a string that includes three surrogate pairs: GREEK ACROPHONIC FIVE TALENTS (U+10148) from the Supplementary Multilingual Plane, U+20026 from the Supplementary Ideographic Plane, and U+F1001 from the private user area. The UTF-16 encoding of each character is a surrogate pair that consists of a high surrogate followed by a low surrogate.
