TYPO3 Core

I can confirm the problem and I think it's either a bug or a misconception - or both.

Just put a file in fileadmin with name 'example-öäü.jpg' and you will see several problems. It doesn't work in BE and not in FE.

Please don't tell me not to use umlauts in filenames, we have 2016 and a software that doesn't work with umlauts in filenames is just buggy.

FileReference has a method publicUrl() which url encode the path. The problem is that all the code that just want to access the file (eg. for image processing) uses that method. Obviously that fails because there is no file example-%C3%B6%C3%A4%C3%BC.jpg in the filesystem.

Why is publicUrl() used everywhere? Because there's no method publicFilePath() - at least not when I had a look.

If you need the file path for processing etc use $file->getForLocalProcessing().

The publicUrl is intended to be used as url so thats why it's rawurlencoded.

TYPO3 can handle these characters in filenames. But you need to be sure that [SYS][UTF8filesystem] = 1 is set in the install tool.
