Module development and code questions

Hi, guys:

I had used the Mail.module in my site for a while. I found that the letters it send in utf-8 coding would have a correct mail body, but the subject and sender's name(site name) would change to bad code.

This bug make me craze, because all my sending letters would be looked like spam and the receivers would put them into junk-mail box!

I really need this module in my utf-8 coding site. Anyone please helping me to fix this problem?

When the visitors register, they need to input their e-mail address, and the system will show "Your password and further instructions have been sent to your e-mail address.". But my system also gives me an error message: "image_exact: the file does not exist". What happened? I try to find the answer here, and find some patchs, but it seems no use. Can someone tell me where I can get the solution or what should I do? Thank you!!

I'm creating a tabbed menu and I'm passing the node ID as part of the path for each menu item. It works find for all but the default menu item, in which case the arguments are stripped off the path for some reason. I've run across this before and was able to work around it, but this time, I don't want to work around it. Is there a logical explanation for that or a way to have the argument passed to the callback?

Thanks in advance.

I can't find the gsitemap module anywhere, is it still available? and if so wherere at.

How do I create a a cck field that allows for array submissions?

For example, a form that allows for unlimited children of a field.

So you could have variable arrays of items on forms.
