+* The UTF-8 output of grotty has strange characters for the minus, the
+  hyphen, and the right quote.  Why?
+
+The used Unicode characters (U+2212 for the minus sign and U+2010 for
+the hyphen) are the correct ones, but many programs can't search them
+properly.  The same is true for the right quote (U+201D).  To map those
+characters back to the ASCII characters, insert the following code
+snippet into the `troffrc' configuration file:

+.  char  - \N'45'
+.  char  ' \N'39'
