Convert the characters in item into glyphs.
This is similar to [[email protected]_with_flags], except it takes a `PangoItem` instead of separate item_text and
analysis arguments. It also takes log_attrs, which may be used in implementing text transforms.
Note that the extra attributes in the analyis that is returned from [[email protected]] have indices that are relative to
the entire paragraph, so you do not pass the full paragraph text as paragraph_text, you need to subtract the item offset from
their indices before calling [[email protected]_with_flags].
