The PDF Maker justifies text this way.

It looks strange to me, since PDF is considered to be a subset of
PostScript feature-wise, and PDF allows you to just set the char-
For example, this is a justified line created by PDF Maker:
0.239095357142857 Tw 0.03347335 Tc
[(Suppor) -40 (t f) 30 (or custom f) 30 (onts w) 10
(ould definitely require w) 10 (or) -15 (k to be added;)
50 ( justification and r) -15 (ight alignment)] TJ
Tw sets the word spacing, Tc the character spacing. The numbers in
the text are for kerning.
