Character spacing controls the minimum amount of space between two glyphs after they have been kerned.
Normally, the glyphs are arranged next to each other without a gap, but you can alter the tracking (space between characters) in this editable field to create spaced lettering for emphasis etc., if you like.
You can choose whether the character spacing should use an
absolute value in the current font measurement system (set in
units of measurement in the Page module), or be a percentage of
the font height. Swap between points or mm and percent by clicking on
the unit abbreviation after the numeric field. The value will be
recalculated immediately as well.
To enter a value, click on the number field, use the [Esc] key to clear the line, enter a new value, and press [Return].
