  Huh ... turns out I should have searched for 'IDN' instead of 'punycode'. 
The code is for Lua 5.2---it will take a bit of work to get it working for
Lua 5.3 but that still leaves normalization issues.  I'm working with the
GNU libidn right now because it can do normailzation, otherwise, I can get
two different IDNs for the same (visually) domain:

	résumé	resume-jxde
	résumé	rsum-bpad
