Hi Hans,

I'm doing some further experiments with the utf and lpeg libraries. This code fails, and I don't understand why:

local s = "Ä"

print(characters.uccode(s))

mtxrun --script test.lua

./test.lua:3: attempt to index global 'characters' (a nil value) mtxrun has al the basic modules in it but not the character ones (thinking of it, i can add an autoload for that, maybe i should do that)

so you need: require "char-ini" local s = "Ä" print(characters.uccode(s)) which will load char-def.lua (you really don't want that in mtxrun.lua embedded) and char-ini.lua Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
