* Create an iterator over the UnicodeString referred to by "textStr".
* The UnicodeString object is copied.
* The iteration range begins with the code unit specified by
- * "textBegin" and ends with the code unit BEFORE the code unit specfied
+ * "textBegin" and ends with the code unit BEFORE the code unit specified
* by "textEnd". The starting position is specified by "textPos". If
* "textBegin" and "textEnd" don't form a valid range on "text" (i.e.,
* textBegin >= textEnd or either is negative or greater than text.size()),
