Extend Subversion repository with UTF-8 paths (#4326)

Provide some test data for UTF-8 encoded paths with Subversion.
This confirms the tests of PR #4324.

Side note:
OS X will decompose some unicode characters into two characters.
For example, the LATIN SMALL LETTER O WITH DIAERESIS (U+00F6 `ö`) will be
decomposed into o and COMBINING DIAERESIS (U+0308).

This obviously breaks SVN path mapping and while you will be able to
commit files with decomposed paths, it will wreak havoc when using these
characters on repositories manipulated by OSX and other systems.
It apepars that Windows, Linux silently ignore these changes.

We can't really account for this server side, but unicode-path patches exists for Subversion on OSX.
For git, a config setting exists that does just that (`core.precomposeunicode`).
