+      GNOME Character Map is a Unicode character map program, part of GNOME desktop.
+      This program allows characters to be displayed by unicode block or script type.
+      It includes brief descriptions of related characters and occasionally meanings
+      of the character in question.
+    </_p>
+    <_p>
+      Gucharmap can also be used to input or enter characters (by copy and paste).
+      The search functionality allows the use of several search methods, including
+      by unicode name or code point of the character.
