Symbolic links for tests data are not taken into account

Hi,

I use planemo version 0.75.7 to test my galaxy apps.
For each app, I have a test-app directory where there are some symbolic links that link to files in a directory above.
When I used the version of 0.75.3 of planemo, the symbolic links were well taken into account but with the last version, the symbolic links are not taken into account : the test files are not found anymore.
If I go back to the 0.75.3 version, there is an error message about unicode symbols...

What is the solution so that my tests still run ?
A solution would be to move all symbolic links to actual files but there is a lot of files and it makes not easy the maintenance...
