Wt

When constructing a WMenuItem, this calls setText(). In case that there isn't a custom path component (which is always the case during construction), the internal path component is automatically generated from the text content.
This always does a narrow() call, to ensure that the component is URL-safe. While not necessarily a bad approach, this will produce a warning log in case character are not supported.

The generation of the path component ought to be delayed until it is enabled.
