  26  Function needed because py2exe python apps crashes horribly if the application is
  27   in a non-us-ascii folder.  (this is actually a windows python problem with "import")
  28
  29   this function is not coded to cleanly handle codepage/locale/UTF.
  30   The value of argv is not necessarily exactly what was passed....instead.....
  31  We will make two checks instead (yes, it is a hack):
  32  1  a char-by-char examination of the passed parameter to ensure 32 >= char <= 127
  33  2 A call to access() to check for folder exists  (This check catches most situations
  34     with accented chars but will obviously NOT fail if an accented and non-accented
  35     folder actually exists.
  36
  37  In summary, this function is a hack and not 100% reliable, but hopefully will be
  38   good enough to identify problems for most first-time users.
