IntelliJ patches mangling my surname

For some reason, IntelliJ generated patches are getting my surname wrong, i.e. :

@author Galder Zamarre<96>o

I checked the file encoding of these files and this is set to UTF-8. The default encoding for the plattform is UTF-8 as well.

In the original file, the line appears as:

@author Galder Zamarreño

I'm having issues when trying to apply the patch to another IntelliJ project.

Any idea how to solve the issue? I tried 'svn diff' and did generate the patch with ñ.

Cheers,
