character set clarification, please?

Section 11.1 of the PowerLoom Manual (Version 1.40) says:

  A word is a contiguous sequence of characters, which include
  all upper case letters, lower case letters, digits and alpha
  characters (ASCII character set from 93 to 128) excluding
  some special characters like white spaces, single and double
  quotes and brackets.

<grumble>
This is rather ambiguous, where it isn't simply nonsensical
(there _is_ no character 128 in (US)ASCII).
</grumble>


Here, for reference, is the ASCII character set:

  0 nul    1 soh    2 stx    3 etx    4 eot    5 enq    6 ack    7 bel
  8 bs     9 ht    10 nl    11 vt    12 np    13 cr    14 so    15 si
 16 dle   17 dc1   18 dc2   19 dc3   20 dc4   21 nak   22 syn   23 etb
 24 can   25 em    26 sub   27 esc   28 fs    29 gs    30 rs    31 us
 32 sp    33  !    34  "    35  #    36  $    37  %    38  &    39  '
 40  (    41  )    42  *    43  +    44  ,    45  -    46  .    47  /
 48  0    49  1    50  2    51  3    52  4    53  5    54  6    55  7
 56  8    57  9    58  :    59  ;    60  <    61  =    62  >    63  ?
 64  @    65  A    66  B    67  C    68  D    69  E    70  F    71  G
 72  H    73  I    74  J    75  K    76  L    77  M    78  N    79  O
 80  P    81  Q    82  R    83  S    84  T    85  U    86  V    87  W
 88  X    89  Y    90  Z    91  [    92  \    93  ]    94  ^    95  _
 96  `    97  a    98  b    99  c   100  d   101  e   102  f   103  g
104  h   105  i   106  j   107  k   108  l   109  m   110  n   111  o
112  p   113  q   114  r   115  s   116  t   117  u   118  v   119  w
120  x   121  y   122  z   123  {   124  |   125  }   126  ~   127 del

Could someone please clarify the _exact_ set of characters that can
be found in a PowerLoom "word"?  Inquiring minds need to know...


I am particularly confused by the restriction on single quotes, given
that the document only defines strings in terms of double quotes:

  A string <string> is a character sequence including words plus all
  special charcters [sic] (except double quotes) enclosed in double
  quotes.  A double quote can be included in a string if it is
  preceeded [sic] by the escape character ''.
