Umlauts in asset file-paths - Broken filenames on server I have some issues with the asset handling of files containing Umlauts. Specifically it seems that the uploaded files on the server get renamed to a "broken" filename.

Zweigänger-1960.jpg becomes ZweigaÌnger-1960.jpg

No issues in the DB fields.

What could be the reason for that? What I'm overlooking? Also a solution similar to "limitAutoSlugsToAscii" would work for me or even renaming the files according to a pattern.
I ran into the same problem lately, but got no clues from the accepted answer. 

As of Craft 2.4 though, is a config setting that limits asset filenames to ASCII, so I'm happy with this workaround:

'convertFilenamesToAscii' =&gt; true 

When storing assets in folders derived from the entry slug, you will additionally need to add the following:

'limitAutoSlugsToAscii' =&gt; true

Minor hassle: These settings naturally won't rename existing files and entries, so you need to touch each one in the control panel to take effect.

(I'm not completely convinced this filename issue is Craft's fault, since the file paths are broken/garbled in Coda, Safari and Safari for iOS – but work just fine in Firefox and Chrome by way of in-browser url-encoding.)
