+Subject: [PATCH] src/oping.c: always use "%s"-style format for
+ printf()-style functions
+
+`ncuses-6.3` added printf-style function attributes and now makes
+it easier to catch cases when user input is used in palce of format
+string when built with CFLAGS=-Werror=format-security:
+
+    oping.c:1265:41: error: format not a string literal and no format arguments [-Werror=format-security]
+     1265 |                                         hist_symbols_utf8[index]);
+          |                                         ^~~~~~~~~~~~~~~~~
+
+Let's wrap all the missing places with "%s" format.
