Blocks names are given with the C<In> prefix. For example, the
-Katakana block is referenced via C<\p{InKatakana}. The C<In>
+Katakana block is referenced via C<\p{InKatakana}>. The C<In>
prefix may be omitted if there is no nameing conflict with a script
or any other property, but it is recommended that C<In> always be used
to avoid confusion.
