193 We can do this because we know a great deal about the sorts of
194 things we are going to be indexing.
196 The current implementation is as follows:
198 ascii[0-159] is used for ASCII and Control-1 characters.
200 level1[0 .. (NUM_LEADING_BYTES-1)] indexes charsets by leading
201 byte (subtract MIN_LEADING_BYTE from the leading byte). If the
202 value of this is not an opaque, then it specifies a value for all
203 characters in the charset. Otherwise, it will be a
204 96-Lisp-Object opaque that we created, specifying a value for
205 each row. If the value of this is not an opaque, then it
206 specifies a value for all characters in the row. Otherwise, it
207 will be a 96-Lisp-Object opaque that we created, specifying a
208 value for each character.
210 NOTE: 1) This will fail if some C routine passes an opaque to
211 Fput_char_table(). Currently this is not a problem
212 since all char tables that are created are Lisp-visible
213 and thus no one should ever be putting an opaque in
214 a char table. Another possibility is to consider
