I guess that's what confuses to_i. Your strings contain characters that *look* like numbers to us, but are not treated as such by to_i. I'm afraid even the parsing capabilities of Date won't solve the problem. It will probably expect digits that are in their ASCII positions rather than Unicode characters that happen to look like numbers to us :) . -- Christophe Grandsire. http://rainbow.conlang.free.fr It takes a straight mind to create a twisted conlang.
