title: Can't set marks in VIM (apostrophe is set as a mark)
body: <p>I am having a problem setting marks in vim. For starters, I have a US International Keyboard, so I use <kbd>'</kbd>+<kbd>a</kbd> to write "á". This means that In vim, to access to the mark "a" I have to write <kbd>'</kbd>+<kbd>space</kbd>+<kbd>a</kbd>, and I am fine with that. Except that it doesn't work. Even if I use another letter, for example "b", the cursor jumps anywhere but to my mark (it doesn't mather if I use <kbd>'</kbd> or <kbd>`</kbd>.</p>
  
  <p>When I see the marks with the command <code>:marks</code>, the <code>'</code> (apostrophe) is usually set as a mark to some random (or at least I can't find a pattern), line in the buffer. And I can't seem to delete that mark.</p>
  
  <p>Does anyone have some information regarding this?</p>
  
  <p>Thanks!</p>
