+
+The resolved levels are produced by the Emacs bidi reordering engine
+that implements the UBA, the Unicode Bidirectional Algorithm. Please
+read the Unicode Standard Annex 9 (UAX#9) for background information
+about these levels.
+
+VPOS is the zero-based number of the current window's screen line
+for which to produce the resolved levels. If VPOS is nil or omitted,
+it defaults to the screen line of point. If the window displays a
+header line, VPOS of zero will report on the header line, and first
+line of text in the window will have VPOS of 1.
+
+Value is an array of resolved levels, indexed by glyph number.
+Glyphs are numbered from zero starting from the beginning of the
+screen line, i.e. the left edge of the window for left-to-right lines
+and from the right edge for right-to-left lines. The resolved levels
+are produced only for the window's text area; text in display margins
+is not included.
+
+If the selected window's display is not up-to-date, or if the specified
+screen line does not display text, this function returns nil. It is
+highly recommended to bind this function to some simple key, like F8,
+in order to avoid these problems.
