I've seen that myself. It happens since Trac was updated. For non-Unicode encoding Trac defaults to ASCII, which supports only 127 chars. Files that contain other chars like Umlauts or IBM frame chars lead to the described error (instead of simply displaying these files).

That doesn't happen on checking these files out with svn or on ​browsing the repository.

I'm still not sure how to handle this. I think the best solution is to assign cp850 to each file.

[Andreas Schnellbacher]

BTW: The file ​nlsdeu.rch contains only ASCII chars. The error message seems to be just wrong. Now I understand why the net is full of reports about that bahavior.

There is nothing that can be done about this error (at least that's what Adrian Gschwend told me). This error exists for every Netlabs repository. Strange enough, it only exists for "old" revisions of files.

[Andreas Schnellbacher]

Thanks, Lars. I found that a few old files behave OK, but no newer file.

Resolving this as invalid, because it's caused by Trac or a plugin.

[Andreas Schnellbacher]

Because many other projects are not affected, I have now the idea that this may be caused by setting:

svn propset -R svn:keywords "Date Revision Author HeadURL Id" *

to fill the $Id:...$ line (from CVS) with data.

[Andreas Schnellbacher]

An last addition: On netlabs.org trac, no .cmd file can be viewed. That doesn't depend on the project.

Things like this show that the problem lies on the trac server side. I can't do anything within the project.
