Interword spacing

Sets the minimum and maximum preferred interword space, expressed as a percentage of the current font size. For example, a setting of 30-60% will (for a 20pt font) set an interword space of 6pt (30% of 20pt) in unjustified text, and between 6pt and 12pt in justified text.

If hyphenation is enabled, it will be invoked to avoid assigning more than the maximum specified interword space.

With the exception of the $document mapping, any mapping can inherit the current interword space setting.

A valid interword space ranges from 10% through to 250%.

You can also set the minimum and maximum interword space using the resolved string value of an attribute variable or user variable and where that value specifies a valid minimum and optional maximum interword space using the format described above.
