Right now I'm using a book to learn Japanese and the latest topic is numbers.
It tells me that some numbers have unlucky meanings. First let me say I don't wish to offend anyone but I need to understand properly. I get that the main unlucky numbers are し which can mean death and く which can mean suffering. The book also tells me there are different versions for these numbers like よn and きゅ (hope I spelt those right). So my question is should I avoid the bad versions of these words completely when counting in Japanese? The only time they appear in my book are when counting from 1 to 10. At all other times the other form is used ( is this acceptable?).

I am also a little confused because there are different versions of 0 and 7 but they don't say that they are unlucky. Any ideas? are these unlucky numbers? Which version of 0 is most common in Japan ( れい or まる or ぜろ ?)

Thanks in advance if anyone can help.
