+Subject: [PATCH] Avoid undefined 'isdigit()' behaviour
+
+As the C11 standard says in section 7.4, 1),
+the 'isdigit()' function is only well-defined
+under this precondition:
+
+> The header <ctype.h> declares several functions
+> useful for classifying and mapping characters.
+> In all cases the argument is an int, the value of
+> which shall be representable as an unsigned char or
+> shall equal the value of the macro EOF. If the argument
+> has any other value, the behavior is undefined.
+
+Therefore avoid to use the 'isdigit()' function here,
+since the Gdk key codes and thus the 'keyval'
+member from the 'GdkEventKey' do not always fulfill
+this requirement and the behaviour is thus undefined.
