        words by saying words that begin with the final letter(s) of the
        previous word.
+       * IRC messages are not UTF-8: Most of the string processing across
+       rbot is done against IRC messages, which do not have a well-defined
+       encoding. Although many clients are now using UTF-8, there is no
+       guarantee that an arbitrary string received from IRC will be UTF-8
+       encoded. We have to force ASCII (byte-wise/charset agnostic) matching
+       because otherwise some strings can give problems: in particular, for
+       example, the bytesequence "\340\350\354\362\371" (that is the aeiou
+       vowels, each with a grave accent) will cause the string to be
+       considered up to the "\354" (i with grave accent) only: so either the
+       rest of the message is ignored, or the matching fails.
