Text Formatting ⇒ Minimum limit for inter-word spacing

[iliafine]

Hi,

In my article, I want Latex never produced inter-word space less than the width of a small letter "m" in the current font. Is there a simple way to achieve that?

Thanks,
Ilia.

With pdfLaTeX there might be a way using microtype and setting the tracking. With Xe- and LuaLaTeX fontspec's WordSpace option may be used.

A manual solution would involve changing \fontdimen2, \fontdimen3 and \fontdimen4.
