205 We can do this because we know a great deal about the sorts of
206 things we are going to be indexing.
208 The current implementation is as follows:
210 ascii[0-159] is used for ASCII and Control-1 characters.
212 level1[0 .. (NUM_LEADING_BYTES-1)] indexes charsets by leading
213 byte (subtract MIN_LEADING_BYTE from the leading byte). If the
214 value of this is not an opaque, then it specifies a value for all
215 characters in the charset. Otherwise, it will be a
216 96-Lisp-Object opaque that we created, specifying a value for
217 each row. If the value of this is not an opaque, then it
218 specifies a value for all characters in the row. Otherwise, it
219 will be a 96-Lisp-Object opaque that we created, specifying a
220 value for each character.
222 NOTE: 1) This will fail if some C routine passes an opaque to
223 Fput_char_table(). Currently this is not a problem
224 since all char tables that are created are Lisp-visible
225 and thus no one should ever be putting an opaque in
226 a char table. Another possibility is to consider
