101 * for example, the return value of pango_unichar_direction()
102 * and pango_find_base_dir() cannot be %PANGO_DIRECTION_WEAK_LTR
103 * or %PANGO_DIRECTION_WEAK_RTL, since every character is either
104 * neutral or has a strong direction; on the other hand
105 * %PANGO_DIRECTION_NEUTRAL doesn't make sense to pass

108 * The %PANGO_DIRECTION_TTB_LTR, %PANGO_DIRECTION_TTB_RTL
