Boggle: What is the dice configuration for Boggle in various languages?
This French page gives the following configuration for a 16 die Boggle version:

ETUKNO EVGTIN DECAMP IELRUW
EHIFSE RECALS ENTDOS OFXRIA
NAVEDZ EIOATA GLENYU BMAQJO
TLIBRA SPULTE AIMSOR ENHRIS

According to this French wikipedia article it is the configuration for the 'international' edition of Boggle.

I assume it is also the configuration for the Portugese 16-die version, since it is used for a Portugese Excel version of Boggle (see here).
