    tdf#105286 use alternative font when glyph is not vertical.
    
    In vertical layout, a vertical font is selected. For windows,
    that means prepending a '@' to the font name. Switch back to
    the one without '@' in order to display characters that needs
    to be rotated 90 degrees in vertical layout correctly.
    
    cherry-picked from aa9251103a131880afa621501936603d8c75af9d.
