175 We can do this because we know a great deal about the sorts of
176 things we are going to be indexing.
178 The current implementation is as follows:
180 ascii[0-159] is used for ASCII and Control-1 characters.
182 level1[0 .. (NUM_LEADING_BYTES-1)] indexes charsets by leading
183 byte (subtract MIN_LEADING_BYTE from the leading byte). If the
184 value of this is not an opaque, then it specifies a value for all
185 characters in the charset. Otherwise, it will be a
186 96-Lisp-Object opaque that we created, specifying a value for
187 each row. If the value of this is not an opaque, then it
188 specifies a value for all characters in the row. Otherwise, it
189 will be a 96-Lisp-Object opaque that we created, specifying a
190 value for each character.
192 NOTE: 1) This will fail if some C routine passes an opaque to
193 Fput_char_table(). Currently this is not a problem
194 since all char tables that are created are Lisp-visible
195 and thus no one should ever be putting an opaque in
196 a char table. Another possibility is to consider
