The problem is that you're using the 'intl' variant of the 'us' keymap, which gives you what are known as "dead keys" - i.e. some punctuation characters turn into modifiers that attach accent marks to the next character, so that for example 'e might give you e-acute. Clearly this isn't what you want.
You mentioned that the installer told you that the detected keyboard layout was "us-en". Are you sure that's entirely accurate? I don't think it can ever say exactly that. I wonder if perhaps it said "us:intl" instead?
Would it be possible for you to boot the Feisty alternate CD again, go through keyboard layout detection, and note down exactly what you did? I can then go through that in more detail. You can press the reset button after keyboard detection, and it won't touch your existing installation in any way.
