title: Checking case-sensitivity of a volume filesystem without writing to it?
body: <p>As the title says: is there any cross-platform way of checking filesystem case-sensitivity for a volume without writing to it?</p>
  
  <p>This is for a cross-platform application so I can't use windows specific APIs, and the filesystem might be read-only, so I can't do the "trick" of writing a file with a guid name in lowercase and check if it exists in upper case.</p>
  
  <p>Is there any API for it that I may have skipped?</p>
