Here's the function I use, which works for both Mac and Windows:

function stsFormatPath pPath,pPlatform
  -- assumes a full "/"-delimited path
  switch pPlatform
  case "MacOSX"
  case "Unix"
    put "\" & space & quote & "'`<>!;()[]?#$^&*=" into tSpecialChars
    repeat for each char tChar in tSpecialChars
      replace tChar with ("\" & tChar) in pPath
    end repeat
    break
  case "Win32"
    set the itemDel to "/"
    put item -1 of pPath into tFile
    put "\/:*?" & quote & "<>|" into tSpecialChars
    repeat for each char tChar in tSpecialChars
      replace tChar with ("-") in tFile
    end repeat
    put tFile into item -1 of pPath
    replace "/" with "\" in pPath
    break
  end switch
  return pPath
end stsFormatPath

Hope this helps,
