TYPO3 Core

I configured the route of an extension's single page in my config.yaml of the site management with the help of the PersistedPatternMapper:

routeEnhancers:
      Person:
        type: Extbase
        limitToPages: [67]
        extension: Person
        plugin: Pi1
        routes:
        - { routePath: '/{name}', _controller: 'Person::show', _arguments: {'name': 'person'} }
        aspects:
          name:
            type: PersistedPatternMapper
            tableName: 'tx_person_domain_model_person'
            routeFieldPattern: '^(?P<given_name>.+)-(?P<last_name>.+)$'
            routeFieldResult: '{given_name}-{last_name}'

I am facing now two problems:

• In the generated URL for the single page the result ({given_name}-{last_name}) is not in lower case like the other parts of the slug (the result is e.g. "John-Doe" instead of "john-doe").
• When using umlauts the slug is e.g. "Mäx-Müstermänn" instead of "maex-muestermaenn".

Hint: In the given example the < and > chars are converted from Redmine to &lt; and &gt;.
