+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/8356
+TITLE:       Make Trace use HEX representation for parameter values of types [VAR]CHAR CHARACTER SET OCTETS and [VAR]BINARY
+DESCRIPTION:
+NOTES:
+    [21.01.2025] pzotov
+    After fix parameters type '[va]rchar(N) character set octets' is shown in the trace as '[var]binary(N)'.
+
+    Confirmed problem on 6.0.0.585: parameter values in the trace are shown in binary (non-readable) form.
+    Checked on 6.0.0.590-7e96b33 - all fine.
