In version 3.14 this

```auto
$replace(%title%,/,_,?,§,:,..,",'''',?,%)

```

cannot be executed as the `Format string` for the `Tag - Filename` icon, while in version 3.12 this code can be executed

This is an invalid format string because it uses an unescaped single percent sign as last parameter. You'd have to use `'%'`. The last pair is also obsolete as the `?` is already replaced by `§`.

That

```auto
$replace(%title%,/,_,?,§,:,..,",'''')

```

checks out
