gtk-text-buffer-get-slice (buffer start end &optional include)

buffer -- a gtk-text-buffer object
start -- a gtk-text-iter start of a range
end -- a gtk-text-iter end of a range
include -- a boolean whether to include invisible text

An allocated UTF-8 string.

Returns the text in the range [start, end). Excludes undisplayed text, text marked with tags that set the invisibility attribute, if the include argument is false.

The returned string includes a 0xFFFC character whenever the text buffer contains embedded images, so byte and character indexes into the returned string do correspond to byte and character indexes into the text buffer. Contrast with the gtk-text-buffer-get-text function. Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the text buffer.
