Use StringInfo to Get Specific Characters From A UTF32 String

We saw that you cannot use the normal string index [] to get individual characters from a UTF32 string.  Instead, you need to use the System.Globalization.StringInfo class.

In the example below, we first get a list of indexes to each of the three characters in our UTF32 string.  We then extract index each character separately.

1 2 3 4 5 6 7 8 9 10

s = "A𠈓C"; int n = s.Length;     // 4, because of 4-byte character in middle   // Get locations of text elements int[] indexes = StringInfo.ParseCombiningCharacters(s);  // 0, 1 and 3   // Retrieve single element string nextChar = StringInfo.GetNextTextElement(s, 0);   // A nextChar = StringInfo.GetNextTextElement(s, 1);          // 𠈓 nextChar = StringInfo.GetNextTextElement(s, 3);          // C
