TYPO3 Core

Hello there,

we spotted an issue in the FILES-ContentObject when using umlaute in a filename in TYPO3 6.2. I'd like to stretch that this only happens in the element as described below, other references to this file work without any problems.

Specs:
TYPO3 6.2.31 ELTS
PHP 7.0.20
MySQL 5.6.33

lib.heroSlider = FILES
lib.heroSlider {
    references {
        data = levelmedia:-1,slide
    }
    renderObj = COA
    renderObj {
        10 = IMAGE
        10 {

            file.import.data = file:current:publicUrl
            titleText.data = file:current:title
            altText.data = file:current:title
            stdWrap.typolink.parameter.data = file:current:link
            wrap = <div class="slide-item">|</div>
        }
    }
}

I could outrule an extension that would overwrite the default FILES renderer, so I'm pretty it's something with the core itself.

Regards
Tizian
