200 We can do this because we know a great deal about the sorts of
201 things we are going to be indexing.
203 The current implementation is as follows:
205 ascii[0-159] is used for ASCII and Control-1 characters.
207 level1[0 .. (NUM_LEADING_BYTES-1)] indexes charsets by leading
208 byte (subtract MIN_LEADING_BYTE from the leading byte). If the
209 value of this is not an opaque, then it specifies a value for all
210 characters in the charset. Otherwise, it will be a
211 96-Lisp-Object opaque that we created, specifying a value for
212 each row. If the value of this is not an opaque, then it
213 specifies a value for all characters in the row. Otherwise, it
214 will be a 96-Lisp-Object opaque that we created, specifying a
215 value for each character.
217 NOTE: 1) This will fail if some C routine passes an opaque to
218 Fput_char_table(). Currently this is not a problem
219 since all char tables that are created are Lisp-visible
220 and thus no one should ever be putting an opaque in
221 a char table. Another possibility is to consider
