If anyone reading this and feels uncertain on how this is done, DON'T do this:

    snprintf(dest, sizeof dest, source);   // BAD code do not repeat

that looks great at first sight, just another size-checked way of copying strings, but remember that the third argument to `snprintf()` [1] is of course a `printf()`-style formatting string. So if that `source` argument contains any percent symbols, there's gonna be a party in your computer and both Undefined and Behavior are going to show up. You don't want that.

Instead, if you want to use `snprintf()` for this, remember to do:

    snprintf(dest, sizeof dest, "%s", source);
