Keyboard layout and character set (code page)

Hi, I am a Windows XP user since past 5 years. Now I’m excited to learn about keyboard layouts, character sets, fonts, Unicode, etc. I have read some books as well regarding these and have got some knowledge. But now there is a problem. I wanted to now if in case I specify a particular keyboard layout in Windows XP how can I know what character set (code page) Windows will ascribe to that layout? I already tried searching Google for answer to this question but dint found any.

Can anyone of you please provide me some documentation to understand these aspects more clearly.

Yes, it is available on web. Just check out these two articles to get all your answers about keyboard layout. http://msdn2.microsoft.com/en-us/library/ms913616.aspx
