Returns the text in the range [start,end).
Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is
false. Does not include characters representing embedded images, so byte and character indexes into the
returned string do not correspond to byte and character indexes into the buffer. Contrast with
get_slice.
