Hi John,

I have tried your proposal, but I'm afraid it didn't work well. I mean, 
it found another hyphenation point, but line breaking was also wrong.

I have just accidentally discovered that letterspacing is problematic in 
standard TeX as described in 
http://www.tug.org/TUGboat/Articles/tb29-1/tb91thanh-fonts.pdf.

It might be that soul is a better option with XeTeX.

Thanks for your help,


Pablo
