new
Create a new PangoScriptIter, used to break a string of Unicode text into runs by Unicode script.
No copy is made of @text, so the caller needs to make sure it remains valid until the iterator is freed with method@Pango.ScriptIter.free.
Return
the new script iterator, initialized to point at the first range in the text, which should be freed with method@Pango.ScriptIter.free. If the string is empty, it will point at an empty range.

Parameters
text
a UTF-8 string
length
length of @text, or -1 if @text is nul-terminated
