 =head2 UTF-8 revamp
 
-The handling of Unicode is unclean in many places. For example, the regexp
-engine matches in Unicode semantics whenever the string or the pattern is
-flagged as UTF-8, but that should not be dependent on an internal storage
-detail of the string.
+The handling of Unicode is unclean in many places.  In the regex engine
+there are especially many problems.  The swash data structure could be
+replaced my something better.  Inversion lists and maps are likely
+candidates.  The whole Unicode database could be placed in-core for a
+huge speed-up.  Only minimal work was done on the optimizer when utf8
+was added, with the result that the synthetic start class often will
+fail to narrow down the possible choices when given non-Latin1 input.
