check code scanning alert

[zdravkov]

we just added a code scanning for the code and an issue was alerted so we need to check it - https://github.com/telerik/kendo-intl/security/code-scanning/1

The warning claims an incomplete string escaping when using replace and possible miss in the escaping, yet in the logic here we are not sanitising but rather deliberately playing with the format string and replacing only a deliberately chosen character for the sake of the format logic.
