s is not defined about data-preparation-for-ctd2

[bence-szalai]

yes, it was missing - strange for not rising an error for me, probably during testing the code I already defined s. Anyway thank you very much for testing it, putting s=0 there solves the problem, :)

utf-8 encoding seems to fix this!
